$PATH and $(pwd) does not mix very well, because PATH is a colon
separated list of directories, but on Windows port of the shell
Git-for-Windows uses, $(pwd) looks like "D:/path/to/a/directory".
With $PWD, we would get /d/path/to/a/directory instead, which would
fit better on $PATH. This broke Windows CI job.
While at it, drop unnecessary use of "env VAR=VAL" before "git
commit"; one-shot export "VAR=VAL git commit" is sufficient.

In 4e43b7ff (Declare both git-switch and git-restore experimental,
2019-04-25), the newly introduced git-switch(1) and git-restore(1)
commands were marked as experimental. This was done to provide time to
make breaking changes to the interface. It has now been over six years
since these commands were implemented and there hasn't been much change.
Consequently, users have grown to rely on how these commands work and it
is no longer feasible to make any breaking changes.
Let's remove the experimental label for git-switch(1) and
git-restore(1).

In the commit 51511d68f4 (for-each-ref: introduce a '--start-after'
option, 2025-07-15), for introducing the '--start-after' flag, the
`ref_iterator_seek()` was modified to also accept a flag. This was to
allow the function to also set the prefix when
'REF_ITERATOR_SEEK_SET_PREFIX' was set.
In `do_filter_refs()` instead of passing the flag, we pass in '1' which
is the value of the flag. While this works, this is definitely hard to
read and introduces inconsistency. Change it to use the flag.
While here, remove the unnecessary 'if (prefix)' clause in the 'else'
statement, since the block already checks for 'prefix'.

Improve the 'git-for-each-ref(1)' documentation with two corrections:
1. Add parentheses around `--exclude=<pattern>` to indicate this option
can be repeated as a complete unit.
2. Move `--stdin | <pattern> ...` to the end, after all flags, since
`<pattern>` is a positional argument that should appear last in the
argument list.
While here, change to using the synopsis block which will automatically
format placeholders in italics and keywords in monospace.

The commit 090eb5336c (refs: selectively set prefix in the seek
functions, 2025-07-15) modified the ref-cache iterator to support
seeking to a specified marker without setting the prefix.
The commit adds and uses an integer 'len' to capture the length of the
seek marker to compare with the entries of a given directory. Since the
type of the variable is 'int', this is met with a typecast of converting
a `strlen` to 'int' so it can be assigned to the 'len' variable.
This is whole operation is a bit wrong:
1. Since the 'len' variable is eventually used in a 'strncmp', it should
have been of type 'size_t'.
2. This also truncates the value provided from 'strlen' to an int, which
could cause a large refname to produce a negative number.
Let's do the correct thing here and simply use 'size_t' for `len`.

xdl_hash_record_verbatim uses modified djb2 hash with XOR instead of ADD
for combining. The ADD-based variant is used as the basis of the modern
("GNU") symbol lookup scheme in ELF. Glibc dynamic loader received an
optimized version of this hash function thanks to Noah Goldstein [1].
Switch xdl_hash_record_verbatim to additive hashing and implement
an optimized loop following the scheme suggested by Noah.
