Here-documend is standard, and works in all shells.
Both here-string and here-doc add final newline, which is important
in this case, because $output is without final newline, but we do
want "read" to succeed on the last line as well.
Shells which support here-string:
- bash, zsh, mksh, ksh93, yash (non-posix-mode).
shells which don't, and got fixed:
- ash-derivatives (dash, free/net bsd sh, busybox-ash).
- pdksh, openbsd sh.
- All Schily Bourne shell variants.

Unit-test framework has learned a simple control structure to allow
embedding test statements in-line instead of having to create a new
function to contain them.
* rs/unit-tests-test-run:
t-strvec: use if_test
t-reftable-basics: use if_test
t-ctype: use if_test
unit-tests: add if_test
unit-tests: show location of checks outside of tests
t0080: use here-doc test body
One of the recently-added tests in t7900 exercises git-maintanance(1)
with the `--detach` flag, which causes it to perform maintenance in the
background. We do not wait for the backgrounded process to exit though,
which causes the process to leak outside of the test, leading to racy
behaviour.
Fix this by synchronizing with the process via a separate file
descriptor. This is the same workaround as we use in t6500, see the
function `run_and_wait_for_auto_gc ()`.

git send-email has support for converting shorthand alias names to
canonical email addresses via the alias file. It supports a wide variety
of alias file formats based on popular email program file formats.
Other programs, such as b4, would like the ability to convert aliases in
the same way as git send-email without needing to re-implement the logic
for understanding the many file formats.
Teach git send-email a new option, --translate-aliases, which will
enable this functionality. Similar to --dump-aliases, this option works
like a new mode of operation for git send-email.
When run with --translate-aliases, git send-email reads from standard
input and converts any provided alias into its canonical name and email
according to the alias file. Each expanded name and address is printed
to standard output, one per line.

The reftable code uses a lot of virtual function pointers, but many of
the concrete implementations do not need all of the parameters.
For the most part these are obviously fine to just mark as UNUSED (e.g.,
the empty_iterator functions unsurprisingly do not do anything). Here
are a few cases where I dug a little deeper (but still ended up just
marking them UNUSED):
- the iterator exclude_patterns is best-effort and optional (though it
would be nice to support in the long run as an optimization)
- ignoring the ref_store in many transaction functions is unexpected,
but works because the ref_transaction itself carries enough
information to do what we need.
- ignoring "err" for in some cases (e.g., transaction abort) is OK
because we do not return any errors. It is a little odd for
reftable_be_create_reflog(), though, since we do return errors
there. We should perhaps be creating string error messages at this
layer, but I've punted on that for now.

The object format for repositories can either be configured explicitly
by passing the `--object-format=` option to git-init(1) or git-clone(1),
or globally by setting the `GIT_DEFAULT_HASH` environment variable.
While the former makes sense, setting random environment variables is
not really a good user experience in case someone decides to only use
SHA256 repositories.
It is only natural to expect for a user that things like this can also
be configured via their config. As such, introduce a new config
"init.defaultObjectFormat", similar to "init.defaultBranch", that allows
the user to configure the default object format when creating new repos.
The precedence order now is the following, where the first one wins:
1. The `--object-format=` switch.
2. The `GIT_DEFAULT_HASH` environment variable.
3. The `init.defaultObjectFormat` config variable.
This matches the typical precedence order we use in Git. We typically
let the environment override the config such that the latter can easily
be overridden on an ephemeral basis, for example by scripts.

The configuration of repository formats is split up across two functions
`validate_hash_algorithm()` and `validate_ref_storage_format()`. This is
fine as-is, but we are about to extend the logic to also read default
values from the config. With the logic split across two functions, we
would either have to pass in additional parameters read from the config,
or read the config multiple times. Both of these options feel a bit
unwieldy.
Merge the code into a new function `repository_format_configure()` that
is responsible for configuring the whole repository's format. Like this,
we can easily read the config in a single place, only.
Furthermore, move the calls to `repo_set_ref_storage_format()` and
`repo_set_hash_algo()` into this new function as well, such that all the
logic to configure the repository format is self-contained here.

The object format tests create one-shot repositories that are only used

While our object format tests for git-init(1) exercise tests with all
known formats in t0001, the tests for the ref format don't. This leads
to some missing test coverage for interesting cases, like whether or not
a non-default ref storage format causes us to bump the repository format
version. We also don't test for the precedence of the `--ref-format=`
and the `GIT_DEFAULT_REF_FORMAT=` environment variable.
Extend the test suite to cover more scenarios related to the ref format.

It was reported that creating a stash with `--keep-index
--include-untracked` causes an error when HEAD points to a commit whose
tree is empty:
$ git stash push --keep-index --include-untracked
error: pathspec ':/' did not match any file(s) known to git
This error comes from `git checkout --no-overlay $i_tree -- :/`, which
we execute to reset the working tree to the state in our index. As the
tree generated from the index is empty in our case, ':/' does not match
any files and thus causes git-checkout(1) to error out.
Fix the issue by skipping the checkout when the index tree is empty. As
explained in the in-code comment, this should be the correct thing to do
as there is nothing that we'd have to reset in the first place.
