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.

Remove `git_common_path()` in favor of the `repo_common_path()` family
of functions, which makes the implicit dependency on `the_repository` go
away.
Note that `git_common_path()` used to return a string allocated via
`get_pathname()`, which uses a rotating set of statically allocated
buffers. Consequently, callers didn't have to free the returned string.
The same isn't true for `repo_common_path()`, so we also have to add
logic to free the returned strings.
This refactoring also allows us to remove `repo_common_pathv()` from the
public interface.

The `get_worktree_git_dir()` function returns a string constant that
does not need to be free'd by the caller. This string is computed for
three different cases:
- If we don't have a worktree we return a path into the Git directory.
The returned string is owned by `the_repository`, so there is no
need for the caller to free it.
- If we have a worktree, but no worktree ID then the caller requests
the main worktree. In this case we return a path into the common
directory, which again is owned by `the_repository` and thus does
not need to be free'd.
- In the third case, where we have an actual worktree, we compute the
path relative to "$GIT_COMMON_DIR/worktrees/". This string does not
need to be released either, even though `git_common_path()` ends up
allocating memory. But this doesn't result in a memory leak either
because we write into a buffer returned by `get_pathname()`, which
returns one out of four static buffers.
We're about to drop `git_common_path()` in favor of `repo_common_path()`,
which doesn't use the same mechanism but instead returns an allocated
string owned by the caller. While we could adapt `get_worktree_git_dir()`
to also use `get_pathname()` and print the derived common path into that
buffer, the whole schema feels a lot like premature optimization in this
context. There are some callsites where we call `get_worktree_git_dir()`
in a loop that iterates through all worktrees. But none of these loops
seem to be even remotely in the hot path, so saving a single allocation
there does not feel worth it.
Refactor the function to instead consistently return an allocated path
so that we can start using `repo_common_path()` in a subsequent commit.

As explained in an earlier commit, we're refactoring path-related
functions to provide a consistent interface for computing paths into the
commondir, gitdir and worktree. Refactor the "submodule" family of
functions accordingly.
Note that in contrast to the other `repo_*_path()` families, we have to

up calling `repo_read_gitmodules()` deep down in the callstack, which
may end up modifying the repository.

The functions provided by the "path" subsystem to derive repository
paths for the commondir, gitdir, worktrees and submodules are quite
inconsistent. Some functions have a `strbuf_` prefix, others have
different return values, some don't provide a variant working on top of
`strbuf`s.
We're thus about to refactor all of these family of functions so that
they follow a common pattern:
- `repo_*_path()` returns an allocated string.
- `repo_*_path_append()` appends the path to the caller-provided
buffer while returning a constant pointer to the buffer. This
clarifies whether the buffer is being appended to or rewritten,
which otherwise wasn't immediately obvious.
- `repo_*_path_replace()` replaces contents of the buffer with the
computed path, again returning a pointer to the buffer contents.
The returned constant pointer isn't being used anywhere yet, but it will
be used in subsequent commits. Its intent is to allow calling patterns
like the following somewhat contrived example:
if (!stat(&st, repo_common_path_replace(repo, &buf, ...)) &&
!unlink(repo_common_path_replace(repo, &buf, ...)))
...
Refactor the commondir family of functions accordingly and adapt all
callers.
Note that `repo_common_pathv()` is converted into an internal
implementation detail. It is only used to implement `the_repository`
compatibility shims and will eventually be removed from the public
