b91a2b6594 mv: add check_dir_in_index() and solve general dir check issue
Originally, moving a <source> directory which is not on-disk due
to its existence outside of sparse-checkout cone, "giv mv" command
errors out with "bad source".

Add a helper check_dir_in_index() function to see if a directory
name exists in the index. Also add a SKIP_WORKTREE_DIR bit to mark
such directories.

Change the checking logic, so that such <source> directory makes
"giv mv" command warns with "advise_on_updating_sparse_paths()"
instead of "bad source"; also user now can supply a "--sparse" flag so
this operation can be carried out successfully.

Originally, moving a sparse file into cone can result in unwarned
overwrite of existing entry. The expected behavior is that if the

fail.

707fa2f76a mv: update sparsity after moving from out-of-cone to in-cone
Originally, "git mv" a sparse file from out-of-cone to
in-cone does not update the moved file's sparsity (remove its
SKIP_WORKTREE bit). And the corresponding cache entry is, unexpectedly,
not checked out in the working tree.

Update the behavior so that:
1. Moving from out-of-cone to in-cone removes the SKIP_WORKTREE bit from
   corresponding cache entry.
2. The moved cache entry is checked out in the working tree to reflect
   the updated sparsity.

1143cc01b7 t1092: mv directory from out-of-cone to in-cone
Add test for "mv: add check_dir_in_index() and solve general dir check
issue" in this series.

This change tests the following:

1. mv <source> as a directory on the sparse index boundary (where it
   would be a sparse directory in a sparse index).
2. mv <source> as a directory which is deeper than the boundary (so
   the sparse index would expand in the cache_name_pos() method).

These tests can be written now for correctness, but later the first case
can be updated to use the 'ensure_not_expanded' helper in t1092.

Add corresponding tests to test following situations:

We do not have sufficient coverage of moving files outside
of a sparse-checkout cone. Create new tests covering this
behavior, keeping in mind that the user can include --sparse
(or not), move a file or directory, and the destination can
already exist in the index (in this case user can use --force
to overwrite existing entry).

ec2f6c0cca t6429: fix use of non-existent function
This test had a line reading

    ! test_file_is_empty actual

which was meant to be

    ! test_must_be_empty actual

The test worked despite the error, because even though
test_file_is_empty is a non-existent function, the '!' negated the
return value and made it pass.  It'd be better to avoid the negation,
so something like

    test_file_not_empty actual

would be better, but perhaps it makes even more sense to specify the
number of lines of expected output to make the test a bit tighter.

eb1cd60290 config tests: fix harmless but broken "rm -r" cleanup
The "test_when_finished" cleanup phase added in 4179b4897f (config:
allow overriding of global and system configuration, 2021-04-19) has
never worked as intended, firstly the ".config/git" is a directory, so
we'd need the "-r" flag, but more importantly the $HOME variable
wasn't properly quoted.

We'd thus end up trying to remove the "trash" part of "trash
directory", which wouldn't fail with "-f", since "rm -f" won't fail on
non-existing files.

It's possible that this would have caused an actual failure if someone
had a $HOME with a space character in it, such that our "rm -f" would
fail to remove an existing directory, but in practice that probably
never happened.

Let's fix both the quoting issue, and the other issue cleanup issue in
4179b4897f, which is that we were attempting to clean up
~/.config/git, but weren't cleaing up ~/.gitconfig.

54e51e559e git-rebase.txt: use back-ticks consistently
While inspecting the 'git rebase' documentation, I noticed that it is
inconsistent with how it uses back-ticks (or other punctuation) for
identifying Git commands, command-line arguments, or values for those
arguments.

Sometimes, an argument (like '--interactive') would appear without any
punctuation, causing the argument to not have any special formatting.
Other times, arguments or 'git rebase' itself would have single-quotes
giving a bold look (in the HTML documentation at least).

By consistently using back-ticks, these types of strings appear in a
monospace font with special highlighting to appear more clearly as text
that exists in a command-line invocation of a Git command.

This rather-large diff is the result of scanning git-rebase.txt and
adding back-ticks as appropriate. Some are adding back-ticks where there
was no punctuation. Others are replacing single quotes.

There are also a few minor cleanups in the process, including those
found by reviewers.

14deb585fb pack-objects.h: remove outdated pahole results
The size and padding of `struct object_entry` is an important factor in
determining the memory usage of `pack-objects`. For this reason,
3b13a5f263 (pack-objects: reorder members to shrink struct object_entry,
2018-04-14) added a comment containing some information from pahole
indicating the size and padding of that struct.

Unfortunately, this comment hasn't been updated since 9ac3f0e5b3
(pack-objects: fix performance issues on packing large deltas,
2018-07-22), despite the size of this struct changing many times since
that commit.

To see just how often the size of object_entry changes, I skimmed the
first-parent history with this script:

    for sha in $(git rev-list --first-parent --reverse 9ac3f0e..)
    do
      echo -n "$sha "
      git checkout -q $sha
      make -s pack-objects.o 2>/dev/null
      pahole -C object_entry pack-objects.o | sed -n \
        -e 's/\/\* size: \([0-9]*\).*/size \1/p' \
        -e 's/\/\*.*padding: \([0-9]*\).*/padding \1/p' | xargs
    done | uniq -f1

In between each merge, the size of object_entry changes too often to
record every instance here. But the important merges (along with their
corresponding sizes and bit paddings) in chronological order are:

    ad635e82d6 (Merge branch 'nd/pack-objects-pack-struct', 2018-05-23) size 80 padding 4
    29d9e3e2c4 (Merge branch 'nd/pack-deltify-regression-fix', 2018-08-22) size 80 padding 9
    3ebdef2e1b (Merge branch 'jk/pack-delta-reuse-with-bitmap', 2018-09-17) size 80 padding 8
    33e4ae9c50 (Merge branch 'bc/sha-256', 2019-01-29) size 96 padding 8

(indicating that the current size of the struct is 96 bytes, with 8
padding bits).

Even though this comment was written in a good spirit, it is updated
infrequently enough that it serves to confuse rather than to encourage
contributors to update the appropriate values when the modify the
definition of object_entry.

For that reason, eliminate the confusion by removing the comment
altogether.

5b893f7d81 git-sh-setup.sh: remove "say" function, change last users
Remove the "say" function, with various rewrites of the remaining
git-*.sh code to C and the preceding change to have git-submodule.sh
stop using the GIT_QUIET variable there were only four uses in
git-subtree.sh. Let's have it use an "arg_quiet" variable instead, and
move the "say" function over to it.

The only other use was a trivial message in git-instaweb.sh, since it
has never supported the --quiet option (or similar) that code added in
0b624b4cee (instaweb: restart server if already running, 2009-11-22)
can simply use "echo" instead.

The remaining in-tree hits from "say" are all for the sibling function
defined in t/test-lib.sh. It's safe to remove this function since it
has never been documented in Documentation/git-sh-setup.txt.

2eec463739 git-submodule.sh: use "$quiet", not "$GIT_QUIET"
Remove the use of the "$GIT_QUIET" variable in favor of our own
"$quiet", ever since b3c5f5cb04 (submodule: move core cmd_update()
logic to C, 2022-03-15) we have not used the "say" function in
git-sh-setup.sh, which is the only thing that's affected by using
"GIT_QUIET".

We still want to support --quiet for our own use though, but let's use
our own variable for that. Now it's obvious that we only care about
passing "--quiet" to "git submodule--helper", and not to change the
output of any "say" invocation.

b788fc671b submodule--helper: eliminate internal "--update" option
Follow-up on the preceding commit which taught "git submodule--helper
update" to understand "--merge", "--checkout" and "--rebase" and use
those options instead of "--update=(rebase|merge|checkout|none)" when
the command invokes itself.

Unlike the preceding change this isn't strictly necessary to
eventually change "git-submodule.sh" so that it invokes "git
submodule--helper update" directly, but let's remove this
inconsistency in the command-line interface. We shouldn't need to
carry special synonyms for existing options in "git submodule--helper"
when that command can use the primary documented names instead.

But, as seen in the post-image this makes the control flow within
"builtin/submodule--helper.c" simpler, we can now write directly to
the "update_default" member of "struct update_data" when parsing the
options in "module_update()".

8f12108c29 submodule--helper: understand --checkout, --merge and --rebase synonyms
Understand --checkout, --merge and --rebase synonyms for
--update={checkout,merge,rebase}, as well as the short options that
'git submodule' itself understands.

This removes a difference between the CLI API of "git submodule" and
"git submodule--helper", making it easier to make the latter an alias
for the former. See 48308681b0 (git submodule update: have a
dedicated helper for cloning, 2016-02-29) for the initial addition of
--update.

36d45163b6 submodule--helper: report "submodule" as our name in some "-h" output
Change the user-facing "git submodule--helper" commands so that
they'll report their name as being "git submodule". To a user these
commands are internal implementation details, and it doesn't make
sense to emit usage about an internal helper when "git submodule" is
invoked with invalid options.

Before this we'd emit e.g.:

	$ git submodule absorbgitdirs --blah
	error: unknown option `blah'
	usage: git submodule--helper absorbgitdirs [<options>] [<path>...]
	[...]
And:

	$ git submodule set-url -- --
	usage: git submodule--helper set-url [--quiet] <path> <newurl>
	[...]

Now we'll start with "usage: git submodule [...]" in both of those
cases. This change does not alter the "list", "name", "clone",
"config" and "create-branch" commands, those are internal-only (as an
aside; their usage info should probably invoke BUG(...)). This only
changes the user-facing commands.

The "status", "deinit" and "update" commands are not included in this
change, because their usage information already used "submodule"
rather than "submodule--helper".

I don't think it's currently possible to emit some of this usage
information in practice, as git-submodule.sh will catch unknown
options, and e.g. it doesn't seem to be possible to get "add" to emit
its usage information from "submodule--helper".

Though that change may be superfluous now, it's also harmless, and
will allow us to eventually dispatch further into "git
submodule--helper" from git-submodule.sh, while emitting the correct
usage output.

6e556c412e submodule--helper: rename "absorb-git-dirs" to "absorbgitdirs"
Rename the "absorb-git-dirs" subcommand to "absorbgitdirs", which is
what the "git submodule" command itself has called it since the
subcommand was implemented in f6f8586140 (submodule: add
absorb-git-dir function, 2016-12-12).

Having these two be different will make it more tedious to dispatch to
eventually dispatch "git submodule--helper" directly, as we'd need to
retain this name mapping. So let's get rid of this needless
inconsistency.

0d68ee723e submodule update: remove "-v" option
In e84c3cf3dc (git-submodule.sh: accept verbose flag in cmd_update to
be non-quiet, 2018-08-14) the "git submodule update" sub-command was
made to understand "-v", but the option was never documented.

The only in-tree user has been this test added in
3ad0401e9e (submodule update: silence underlying merge/rebase with
"--quiet", 2020-09-30), it wasn't per-se testing --quiet, but fixing a
bug in e84c3cf3dc: It used to set "GIT_QUIET=0" instead of unsetting
it on "-v", and thus we'd end up passing "--quiet" to "git
submodule--helper" on "-v", since the "--quiet" option was passed
using the ${parameter:+word} construct.

Furthermore, even if someone had used the "-v" option they'd only be
getting the default output. Our default in both git-submodule.sh and
"git submodule--helper" has been to be "verbose", so the only way this
option could have matter is if it were used as e.g.:

    git submodule --quiet update -v [...]

I.e. to undo the effect of a previous "--quiet" on the command-line.

d9c7f69aaa submodule--helper: have --require-init imply --init
Adjust code added in 0060fd1511 (clone --recurse-submodules: prevent
name squatting on Windows, 2019-09-12) to have the internal
--require-init option imply --init, rather than having
"git-submodule.sh" add it implicitly.

This change doesn't make any difference now, but eliminates another
special-case where "git submodule--helper update"'s behavior was
different from "git submodule update". This will make it easier to
eventually replace the cmd_update() function in git-submodule.sh.

We'll still need to keep the distinction between "--init" and
"--require-init" in git-submodule.sh. Once cmd_update() gets
re-implemented in C we'll be able to change variables and other code
related to that, but not yet.

da3aae9e84 git-submodule.sh: remove unused top-level "--branch" argument
In 5c08dbbdf1 (git-submodule: fix subcommand parser, 2008-01-15) the
"--branch" option was supported as an option to "git submodule"
itself, i.e. "git submodule --branch" as a side-effect of its
implementation.

Then in b57e8119e6 (submodule: teach set-branch subcommand,
2019-02-08) when the "set-branch" subcommand was added the assertion
that we shouldn't have "--branch" anywhere except as an argument to
"add" and "set-branch" was copy/pasted from the adjacent check for
"--cache" added (or rather modified) in 496eeeb19b (git-submodule.sh:
avoid "test <cond> -a/-o <cond>", 2014-06-10).

But there's been a logic error in that check, which at a glance looked
like it should be supporting:

    git submodule --branch <branch> (add | set-branch) [<options>]

But due to "||" in the condition (as opposed to "&&" for "--cache") if
we have "--branch" here already we'll emit usage, even for "add" and
"set-branch".

So in addition to never having documented this form, it hasn't worked
since b57e8119e6 was released with v2.22.0.

So it's safe to remove this code. I.e. we don't want to support the
form noted above, but only:

    git submodule (add | set-branch) --branch <branch> [<options>]
