When writing commit-graph files, it can be convenient to ask for all
reachable commits (starting at the ref set) in the resulting file. This
is particularly helpful when writing to stdin is complicated, such as a
future integration with 'git gc'.

If core.commitGraph is true, verify the contents of the commit-graph
during 'git fsck' using the 'git commit-graph verify' subcommand. Run
this check on all alternates, as well.
We use a new process for two reasons:
1. The subcommand decouples the details of loading and verifying a
commit-graph file from the other fsck details.
2. The commit-graph verification requires the commits to be loaded
in a specific order to guarantee we parse from the commit-graph
file for some objects and from the object database for others.

If the commit-graph file becomes corrupt, we need a way to verify
that its contents match the object database. In the manner of
'git fsck' we will implement a 'git commit-graph verify' subcommand
to report all issues with the file.
Add the 'verify' subcommand to the 'commit-graph' builtin and its
documentation. The subcommand is currently a no-op except for
loading the commit-graph into memory, which may trigger run-time
errors that would be caught by normal use. Add a simple test that
ensures the command returns a zero error code.
If no commit-graph file exists, this is an acceptable state. Do
not report any errors.

completion: keep other config var completion in camelCase
completion: drop the hard coded list of config vars
am: move advice.amWorkDir parsing back to advice.c
advice: keep config name in camelCase in advice_config[]
fsck: produce camelCase config key names
help: add --config to list all available config
fsck: factor out msg_id_info[] lazy initialization code
grep: keep all colors in an array
Add and use generic name->id mapping code for color slot parsing
"git diff" compares the index and the working tree. For paths

files. They are now shown as new by default.
"git apply" learned the "--intent-to-add" option so that an
otherwise working-tree-only application of a patch will add new
paths to the index marked with the "intent-to-add" bit.
* nd/diff-apply-ita:
apply: add --intent-to-add

diff: turn --ita-invisible-in-index on by default
diff: ignore --ita-[in]visible-in-index when diffing worktree-to-tree

The bulk of "git submodule foreach" has been rewritten in C.

submodule foreach: correct '$path' in nested submodules from a subdirectory
The other "mode" options of git-branch have short-option
aliases that are easy to type (e.g., "-d" and "-m"). Let's
give "--list" the same treatment.
This also makes it consistent with the similar "git tag -l"
option.
We didn't do this originally because "--create-reflog" was
squatting on the "-l" option. Now that we've deprecated that
use for long enough, we can make the switch.

The "-l" option is short for "--create-reflog". This has
caused much confusion over the years. Most people expect it
to work as "--list", because that would match the other
"mode" options like -d/--delete and -m/--move, as well as
the similar -l/--list option of git-tag.
Adding to the confusion, using "-l" _appears_ to work as
"--list" in some cases:
$ git branch -l
* master
because the branch command defaults to listing (so even
trying to specify --list in the command above is redundant).
But that may bite the user later when they add a pattern,
like:
$ git branch -l foo
which does not return an empty list, but in fact creates a
new branch (with a reflog, naturally) called "foo".
It's also probably quite uncommon for people to actually use
"-l" to create a reflog. Since 0bee591869 (Enable reflogs by
default in any repository with a working directory.,
2006-12-14), this is the default in non-bare repositories.
So it's rather unfortunate that the feature squats on the
short-and-sweet "-l" (which was only added in 3a4b3f269c
(Create/delete branch ref logs., 2006-05-19), meaning there
were only 7 months where it was actually useful).
Let's deprecate "-l" in hopes of eventually re-purposing it
to "--list".
Note that we issue the warning only when we're not in list
mode. This means that people for whom it works as a happy
accident, namely:
$ git branch -l
master
won't see the warning at all. And when we eventually switch
to it meaning "--list", that will just continue to work.
We do the issue the warning for these important cases:
- when we are actually creating a branch, in case the user
really did mean it as "--create-reflog"
- when we are in some _other_ mode, like deletion. There
the "-l" is a noop for now, but it will eventually
conflict with any other mode request, and the user
should be told that this is changing.

Mention that this feature works with some commands (merge and cherry-pick,
implying that it also works with commands that build on these like rebase
-m and rebase -i). Explicitly mentioning two commands hopefully implies
that it may not always work with other commands (am, and rebase without
flags that imply either -m or -i).
Also, since the directory rename detection from this cycle was
specifically added in merge-recursive and not diffcore-rename, remove the
'in "diff" family" phrase from the note. (Folks have requested in the
past that `git diff` detect directory renames and somehow simplify its
output, so it may be helpful to avoid implying that diff has any new
capability here.)

On a daily work with multiple local git branches, the usual way to
submit only a specified commit was to cherry-pick the commit on
master then run git-p4 submit. It can be very annoying to switch
between local branches and master, only to submit one commit. The
proposed new way is to select directly the commit you want to
submit.
Add option --commit to command 'git-p4 submit' in order to submit
only specified commit(s) in p4.
On a daily work developping software with big compilation time, one
may not want to rebase on his local git tree, in order to avoid long
recompilation.
Add option --disable-rebase to command 'git-p4 submit' in order to
disable rebase after submission.

Introduce a checkout.defaultRemote setting which can be used to
designate a remote to prefer (via checkout.defaultRemote=origin) when
running e.g. "git checkout master" to mean origin/master, even though
there's other remotes that have the "master" branch.
I want this because it's very handy to use this workflow to checkout a
repository and create a topic branch, then get back to a "master" as
retrieved from upstream:
(
cd /tmp &&
rm -rf tbdiff &&
git clone git@github.com:trast/tbdiff.git &&
cd tbdiff &&
git branch -m topic &&
git checkout master
)
That will output:
Branch 'master' set up to track remote branch 'master' from 'origin'.
Switched to a new branch 'master'
But as soon as a new remote is added (e.g. just to inspect something
from someone else) the DWIMery goes away:
(
cd /tmp &&
rm -rf tbdiff &&
git clone git@github.com:trast/tbdiff.git &&
cd tbdiff &&
git branch -m topic &&
git remote add avar git@github.com:avar/tbdiff.git &&
git fetch avar &&
git checkout master
)
Will output (without the advice output added earlier in this series):
error: pathspec 'master' did not match any file(s) known to git.
The new checkout.defaultRemote config allows me to say that whenever
that ambiguity comes up I'd like to prefer "origin", and it'll still
work as though the only remote I had was "origin".
Also adjust the advice.checkoutAmbiguousRemoteBranchName message to
mention this new config setting to the user, the full output on my
git.git is now (the last paragraph is new):
$ ./git --exec-path=$PWD checkout master
error: pathspec 'master' did not match any file(s) known to git.
hint: 'master' matched more than one remote tracking branch.
hint: We found 26 remotes with a reference that matched. So we fell back
hint: on trying to resolve the argument as a path, but failed there too!
hint:
hint: If you meant to check out a remote tracking branch on, e.g. 'origin',
hint: you can do so by fully qualifying the name with the --track option:
hint:
hint: git checkout --track origin/<name>
hint:
hint: If you'd like to always have checkouts of an ambiguous <name> prefer
hint: one remote, e.g. the 'origin' remote, consider setting
hint: checkout.defaultRemote=origin in your config.
I considered splitting this into checkout.defaultRemote and
worktree.defaultRemote, but it's probably less confusing to break our
own rules that anything shared between config should live in core.*
than have two config settings, and I couldn't come up with a short
name under core.* that made sense (core.defaultRemoteForCheckout?).

As the "checkout" documentation describes:
If <branch> is not found but there does exist a tracking branch in
exactly one remote (call it <remote>) with a matching name, treat
as equivalent to [...] <remote>/<branch.
This is a really useful feature. The problem is that when you add
another remote (e.g. a fork), git won't find a unique branch name
anymore, and will instead print this unhelpful message:
$ git checkout master
error: pathspec 'master' did not match any file(s) known to git
Now it will, on my git.git checkout, print:
$ ./git --exec-path=$PWD checkout master
error: pathspec 'master' did not match any file(s) known to git.
hint: 'master' matched more than one remote tracking branch.
hint: We found 26 remotes with a reference that matched. So we fell back
hint: on trying to resolve the argument as a path, but failed there too!
hint:
hint: If you meant to check out a remote tracking branch on, e.g. 'origin',
hint: you can do so by fully qualifying the name with the --track option:
hint:
hint: git checkout --track origin/<name>
Note that the "error: pathspec[...]" message is still printed. This is
because whatever else checkout may have tried earlier, its final
fallback is to try to resolve the argument as a path. E.g. in this
case:
$ ./git --exec-path=$PWD checkout master pu
error: pathspec 'master' did not match any file(s) known to git.
error: pathspec 'pu' did not match any file(s) known to git.
There we don't print the "hint:" implicitly due to earlier logic
around the DWIM fallback. That fallback is only used if it looks like
we have one argument that might be a branch.
I can't think of an intrinsic reason for why we couldn't in some
future change skip printing the "error: pathspec[...]" error. However,
to do so we'd need to pass something down to checkout_paths() to make
it suppress printing an error on its own, and for us to be confident
that we're not silencing cases where those errors are meaningful.
I don't think that's worth it since determining whether that's the
case could easily change due to future changes in the checkout logic.
