The pickaxe options, -G and -S, need either a regex or a string to look
through the history for. An empty value isn't very useful since it
would either match everything or nothing, and what's worse, we presently
crash with a BUG like so when the user provides one:
BUG: diffcore-pickaxe.c:241: should have needle under -G or -S
Since it's not very nice of us to crash and this wouldn't do anything
useful anyway, let's simply inform the user that they must provide a
non-empty argument and exit with an error if they provide an empty one
instead.

Add a section for --stdin in the list of options and document that it

zero "git merge-tree" dies before printing it.

Commit 9c93ba4d0ae (merge-recursive: honor diff.algorithm, 2024-07-13)
replaced init_merge_options() with init_basic_merge_config() for use in
plumbing commands and init_ui_merge_config() for use in porcelain
commands. As "git merge-tree" is a plumbing command it should call
init_basic_merge_config() rather than init_ui_merge_config(). The merge
ort machinery ignores "diff.algorithm" so the behavior is unchanged by
this commit but it future proofs us against any future changes to
init_ui_merge_config().

real_merge() only ever returns "0" or "1" as it dies if the merge status
is less than zero. Therefore the check for "result < 0" is redundant and
the result variable is not needed. The return value of real_merge() is
ignored because exit status of "git merge-tree --stdin" is "0" for both
successful and conflicted merges (the status of each merge is written to
stdout). The return type of real_merge() is not changed as it is used
for the program's exit status when "--stdin" is not given.

If a process tries to read the output from "git merge-tree --stdin"
before it closes merge-tree's stdin then it deadlocks. This happens
because merge-tree does not flush its output before trying to read
another line of input and means that it is not possible to cherry-pick a
sequence of commits using "git merge-tree --stdin". Fix this by calling
maybe_flush_or_die() before trying to read the next line of
input. Flushing the output after each merge does not seem to affect the
performance, any difference is lost in the noise even after increasing
the number of runs.

Rename `match_name_with_pattern()` to `match_refname_with_pattern()` to
better reflect its purpose and improve documentation comment clarity.
The previous function name and parameter names were inconsistent, making
it harder to understand their roles in refspec matching.
- Rename parameters:
- `key` -> `pattern` (globbing pattern to match)
- `name` -> `refname` (refname to check)
- `value` -> `replacement` (replacement mapping pattern)

Currently, the "test capability advertisement" test creates some files
with expected content which are used by other tests below it.
To remove that side-effect from this test, let's split up part of
it into a "setup"-type test which creates the files with expected content
which gets reused by multiple tests. This will be useful in a following
commit.

Currently, get_uname_info() function provides the full OS information.
In a following commit, we will need it to provide only the OS name.
Let's extend it to accept a "full" flag that makes it switch between

We may need to refactor this function in the future if an

The git_user_agent_sanitized() function performs some sanitizing to
avoid special characters being sent over the line and possibly messing
up with the protocol or with the parsing on the other side.
Let's extract this sanitizing into a new redact_non_printables() function,
as we will want to reuse it in a following patch.
For now the new redact_non_printables() function is still static as
it's only needed locally.
While at it, let's use strbuf_detach() to explicitly detach the string
contained by the 'buf' strbuf.

Explicitly set the default goal at the very top of various makefiles.
This is already present in some makefiles, but not all of them.
In particular, this corrects a regression introduced in a38edab7c8
(Makefile: generate doc versions via GIT-VERSION-GEN, 2024-12-06). That
commit added some config files as build targets for the Documentation
directory, and put the target configuration in a sensible place.
Unfortunately, that sensible place was above any other build target
definitions, meaning the default goal changed to being those
configuration files only, rather than the HTML and man page
documentation.

Back in 728b9ac0c3 (Makefile(s): avoid recipe prefix in conditional
statements, 2024-04-08), we prepared our Makefiles for a forthcoming
change in upstream Make that would ban the recipe prefix within a
conditional statement by replacing tabs (the prefix) with eight spaces.
In b9d6f64393 (compat/zlib: allow use of zlib-ng as backend,
2025-01-28), a handful of recipe prefix characters were introduced in a
conditional statement ('ifdef ZLIB_NG'), causing 'make' to fail on my
system, which uses GNU Make 4.4.90.
Remove the recipe prefix characters by replacing them with the same
script as is mentioned in 728b9ac0c3.

The -X renormalize (or merge.renormalize config) option is intended to
reduce conflicts due to normalization of newer versions of history. It
does so by renormalizing files that it is about to do a three-way
content merge on. Some folks thought it would renormalize all files
throughout the tree, and the previous wording wasn't clear enough to
dispell that misconception. Update the docs to make it clear that the
merge machinery will only apply renormalization to files which need a
three-way content merge.
(Technically, the merge machinery also does renormalization on
modify/delete conflicts, in order to see if the modification was merely
a normalization; if so, it can accept the delete and not report a
conflict. But it's not clear that this piece needs to be explained to
users, and trying to distinguish it might feel like splitting hairs and
overcomplicating the explanation, so we leave it out.)

We do not seem to centrally document exhaustively ways to spell
Boolean values.
The description in the Environment Variables of git(1) section
assumes that the reader is already familiar with how "Boolean valued
configuration variables" are specified, without referring to
anything, so there is no way for the readers to find out more.
The description of `bool` in the section on "--type
<type>" in "git config --help" might be the place to do so, but it
is not telling us all that much.
The description of Boolean valued placeholders in the pretty formats
section of "git log --help" enumerates the possible values with "etc."
implying there may be other synonyms; shrink the list of samples and
instead refer to the canonical and authoritative source of truth, which
now is git-config(1).

When rebase rewords a commit it picks the commit and then runs "git
commit --amend" to reword it. When the commit is picked the sequencer
tries to reuse existing commits by fast-forwarding if the parents are
unchanged. Rewording an empty commit that has been fast-forwarded fails
because "git commit --amend" is called without "--allow-empty". This
happens because when a commit is fast-forwarded the logic that checks
whether we should pass "--allow-empty" is skipped. Fix this by always
passing "--allow-empty" when rewording a commit. This is safe because we
are amending a commit that has already been picked so if it had become
empty when it was picked we'd have already returned an error.
As "git commit" will happily create empty merge commits without
"--allow-empty" we do not need to pass that flag when rewording merge
commits.

Remove the_repository global variable in favor of the repository
argument that gets passed in "builtin/update-server-info.c".
When `-h` is passed to the command outside a Git repository, the
`run_builtin()` will call the `cmd_update_server_info()` function
with `repo` set to NULL and then early in the function, "parse_options()"
call will give the options help and exit, without having to consult much
of the configuration file. So it is safe to omit reading the config when
`repo` argument the caller gave us is NULL.

The use of "echo -e" is not portable and not specified by POSIX. dash
does not support any options except "-n", and so this script will not
work on operating systems which use that as /bin/sh.
Fortunately, the solution is easy: switch to printf(1), which is
specified by POSIX and allows the escape sequences we want to use. This
will allow the script to work with any POSIX shell.
