We document the delta data as a set of instructions, but forget to
document the two sizes that precede those instructions: the size of the
base object and the size of the object to be reconstructed. Fix this
omission.
Rather than cramming all the details about the encoding into the running
text, introduce a separate section detailing our "size encoding" and
refer to it.

'gitmodules.txt' is a guide about the '.gitmodules' file that describes
submodule properties, and that file must exist at the root of the
repository. This was clarified in e5b5c1d2cf (Document clarification:
gitmodules, gitattributes, 2008-08-31).
However, that commit mistakenly uses the non-existing environment
variable 'GIT_WORK_DIR' to refer to the root of the repository.
Fix that by using the correct variable, 'GIT_WORK_TREE'. Take the
opportunity to modernize and improve the formatting of that guide,
and fix a grammar mistake.

`git worktree repair` knows how to repair the two-way links between the
repository and a worktree as long as a link in one or the other
direction is sound. For instance, if a linked worktree is moved (without
using `git worktree move`), repair is possible because the worktree
still knows the location of the repository even though the repository no
longer knows where the worktree is. Similarly, if the repository is
moved, repair is possible since the repository still knows the locations
of the worktrees even though the worktrees no longer know where the
repository is.
However, if both the repository and the worktrees are moved, then links
are severed in both directions, and no repair is possible. This is the
case even when the new worktree locations are specified as arguments to
`git worktree repair`. The reason for this limitation is twofold. First,
when `repair` consults the worktree's gitfile (/path/to/worktree/.git)
to determine the corresponding <repo>/worktrees/<id>/gitdir file to fix,
<repo> is the old path to the repository, thus it is unable to fix the
`gitdir` file at its new location since it doesn't know where it is.
Second, when `repair` consults <repo>/worktrees/<id>/gitdir to find the
location of the worktree's gitfile (/path/to/worktree/.git), the path
recorded in `gitdir` is the old location of the worktree's gitfile, thus
it is unable to repair the gitfile since it doesn't know where it is.
Fix these shortcomings by teaching `repair` to attempt to infer the new
location of the <repo>/worktrees/<id>/gitdir file when the location
recorded in the worktree's gitfile has become stale but the file is
otherwise well-formed. The inference is intentionally simple-minded.
For each worktree path specified as an argument, `git worktree repair`
manually reads the ".git" gitfile at that location and, if it is
well-formed, extracts the <id>. It then searches for a corresponding
<id> in <repo>/worktrees/ and, if found, concludes that there is a
reasonable match and updates <repo>/worktrees/<id>/gitdir to point at
the specified worktree path. In order for <repo> to be known, `git
worktree repair` must be run in the main worktree or bare repository.
`git worktree repair` first attempts to repair each incoming
/path/to/worktree/.git gitfile to point at the repository, and then
attempts to repair outgoing <repo>/worktrees/<id>/gitdir files to point
at the worktrees. This sequence was chosen arbitrarily when originally
implemented since the order of fixes is immaterial as long as one side
of the two-way link between the repository and a worktree is sound.
However, for this new repair technique to work, the order must be
reversed. This is because the new inference mechanism, when it is
successful, allows the outgoing <repo>/worktrees/<id>/gitdir file to be
repaired, thus fixing one side of the two-way link. Once that side is
fixed, the other side can be fixed by the existing repair mechanism,
hence the order of repairs is now significant.
Two safeguards are employed to avoid hijacking a worktree from a
different repository if the user accidentally specifies a foreign
worktree as an argument. The first, as described above, is that it
requires an <id> match between the repository and the worktree. That
itself is not foolproof for preventing hijack, so the second safeguard
is that the inference will only kick in if the worktree's
/path/to/worktree/.git gitfile does not point at a repository.

git rev-parse has several options which print various paths. Some of
these paths are printed relative to the current working directory, and
some are absolute.
Normally, this is not a problem, but there are times when one wants
paths entirely in one format or another. This can be done trivially if
the paths are canonical, but canonicalizing paths is not possible on
some shell scripting environments which lack realpath(1) and also in Go,
which lacks functions that properly canonicalize paths on Windows.
To help out the scripter, let's provide an option which turns most of
the paths printed by git rev-parse to be either relative to the current
working directory or absolute and canonical. Document which options are
affected and which are not so that users are not confused.
This approach is cleaner and tidier than providing duplicates of
existing options which are either relative or absolute.
Note that if the user needs both forms, it is possible to pass an
additional option in the middle of the command line which changes the
behavior of subsequent operations.

Add a "key_value_separator" option to the "%(trailers)" pretty format,
to go along with the existing "separator" argument. In combination
these two options make it trivial to produce machine-readable (e.g. \0
and \0\0-delimited) format output.
As elaborated on in a previous commit which added "keyonly" it was
needlessly tedious to extract structured data from "%(trailers)"
before the addition of this "key_value_separator" option. As seen by
the test being added here extracting this data now becomes trivial.

Add support for a "keyonly". This allows for easier parsing out of the
key and value. Before if you didn't want to make assumptions about how
the key was formatted. You'd need to parse it out as e.g.:
--pretty=format:'%H%x00%(trailers:separator=%x00%x00)' \
'%x00%(trailers:separator=%x00%x00,valueonly)'
And then proceed to deduce keys by looking at those two and
subtracting the value plus the hardcoded ": " separator from the
non-valueonly %(trailers) line. Now it's possible to simply do:
--pretty=format:'%H%x00%(trailers:separator=%x00%x00,keyonly)' \
'%x00%(trailers:separator=%x00%x00,valueonly)'
Which at least reduces it to a state machine where you get N keys and
correlate them with N values. Even better would be to have a way to
change the ": " delimiter to something easily machine-readable (a key
might contain ": " too). A follow-up change will add support for that.
I don't really have a use-case for just "keyonly" myself. I suppose it
would be useful in some cases as "key=*" matches case-insensitively,
so a plain "keyonly" will give you the variants of the keys you
matched. I'm mainly adding it to fix the inconsistency with
"valueonly".

Change the documentation for the various %(trailers) options so it
isn't repeating part of the documentation for "only" about how boolean
values are handled. Instead, let's split the description of that into
general documentation at the top.
It then suffices to refer to it by listing the options as
"opt[=<BOOL>]". I'm also changing it to upper-case "[=<BOOL>]" from
"[=val]" for consistency with "<SEP>"
It took me a couple of readings to realize that these options were
referring back to the "only" option's treatment of boolean
values.

The 'clean' target is still noticeably slow on cygwin, despite the
substantial improvement made by the previous patch. For example, the
second invocation of 'make clean' below:
$ make clean >/dev/null 2>&1
$ make clean
...
make[1]: Entering directory '/home/ramsay/git/Documentation'
make[2]: Entering directory '/home/ramsay/git'
make[2]: 'GIT-VERSION-FILE' is up to date.
make[2]: Leaving directory '/home/ramsay/git'
...
$
has been timed at 12.364s on my laptop (an old core i5-4200M @ 2.50GHz,
8GB RAM, 1TB HDD).
Notice that the 'clean' target is making a nested call to the parent
Makefile to ensure that the GIT-VERSION-FILE is up-to-date (prior to
the previous patch, there would have been _two_ such invocations).
This is to ensure that the $(GIT_VERSION) make variable is set, once
that file had been included. However, the 'clean' target does not use
the $(GIT_VERSION) variable, directly or indirectly, so it does not
have any affect on what the target removes. Therefore, the time spent
on ensuring an up to date GIT-VERSION-FILE is wasted effort.
In order to eliminate such wasted effort, use the value of the internal
$(MAKECMDGOALS) variable to only '-include ../GIT-VERSION-FILE' when the
target is not 'clean'. (This drops the time down to 10.361s, on my laptop,
giving an improvement of 16.20%).

The 'clean' target is noticeably slow on cygwin, even for a 'do-nothing'
invocation of 'make clean'. For example, the second 'make clean' below:
$ make clean >/dev/null 2>&1
$ make clean
GIT_VERSION = 2.29.0
...
make[1]: Entering directory '/home/ramsay/git/Documentation'
GEN mergetools-list.made
GEN cmd-list.made
GEN doc.dep
...
$
has been timed at 23.339s, using git v2.29.0, on my laptop (an old core
i5-4200M @ 2.50GHz, 8GB RAM, 1TB HDD).
Notice that, since the 'doc.dep' file does not exist, make takes the
time (about 8s) to generate several files in order to create the doc.dep
include file. (If an 'include' file is missing, but a target for the
said file is present in the Makefile, make will execute that target
and, if that file now exists, throw away all its internal data and
re-read and re-parse the Makefile). Having spent the time to include
the 'doc.dep' file, the 'clean' target immediately deletes those files.
The document dependencies specified in the 'doc.dep' include file,
expressed as make targets and prerequisites, do not affect what the
'clean' target removes. Therefore, the time spent in generating the
dependencies is completely wasted effort.
In order to eliminate such wasted effort, use the value of the internal
$(MAKECMDGOALS) variable to only '-include doc.dep' when the target is
not 'clean'. (This drops the time down to 12.364s, on my laptop, giving
an improvement of 47.02%).
