The idea of the `SKIP_DASHED_BUILT_INS` option is to stop hard-linking
the built-in commands as separate executables. The patches to do that
specifically excluded the three commands `receive-pack`,
`upload-archive` and `upload-pack`, though: these commands are expected
to be present in the `PATH` in their dashed form on the server side of
any fetch/push.
However, due to an oversight by myself, even if those commands were
still hard-linked, they were not installed into `bin/`.

When building with SKIP_DASHED_BUILT_INS=YesPlease, the built-in
commands are no longer present in the `PATH` as hardlinks to `git`.
As a consequence, `load_command_list()` needs to be taught to find the
names of the built-in commands from elsewhere.
This only affected the output of `git --list-cmds=main`, but not the
output of `git help -a` because the latter includes the built-in
commands by virtue of them being listed in command-list.txt.
The bug was detected via a patch series that turns the merge strategies
included in Git into built-in commands: `git merge -s help` relies on
`load_command_list()` to determine the list of available merge
strategies.

Since e4597aae6590 (run test suite without dashed git-commands in PATH,
2009-12-02), we stopped running our tests with `git-foo` binaries found
at the top-level directory of a freshly built source tree; instead we
have placed only `git` and selected `git-foo` commands that must be on
`$PATH` in `bin-wrappers/` and prepended that `bin-wrappers/` to the
`PATH` used in the test suite. We did that to catch the tests and
scripted Git commands that still try to use the dashed form.
Since CI jobs will not install the built Git to anywhere, and the
hardlinks we make at the top-level of the source tree for `git-add` and
friends are not even used during tests, they are pure waste of resources
these days.
Thanks to the newly invented `SKIP_DASHED_BUILT_INS` knob, we can now
skip creating these links in the source tree. So let's do that.
Note that this change introduces a subtle change of behavior: when Git's
`cmd_main()` calls `setup_path()`, it inserts the value of
`GIT_EXEC_PATH` (defaulting to `<prefix>/libexec/git-core`) at the
beginning of the environment variable `PATH`. This is necessary to find
e.g. scripted commands that are installed in that location. For the
purposes of Git's test suite, the `bin-wrappers/` scripts override
`GIT_EXEC_PATH` to point to the top-level directory of the source code.
In other words, if a scripted command had used a dashed invocation of a
built-in Git command, it would not have been caught previously, which is
fixed by this change.

For a long time already, the non-dashed form of the built-ins is the
recommended way to write scripts, i.e. it is better to call `git merge
[...]` than to call `git-merge [...]`.
While Git still supports the dashed form (by hard-linking the `git`
executable to the dashed name in `libexec/git-core/`), in practice, it
is probably almost irrelevant.
However, we *do* care about keeping people's scripts working (even if
they were written before the non-dashed form started to be recommended).
Keeping this backwards-compatibility is not necessarily cheap, though:
even so much as amending the tip commit in a git.git checkout will
require re-linking all of those dashed commands. On this developer's
laptop, this makes a noticeable difference:

Also, `.zip` files do not have any standardized support for hard-links,
therefore "zipping up" the executables will result in inflated disk
usage. (To keep down the size of the "MinGit" variant of Git for
Windows, which is distributed as a `.zip` file, the hard-links are
excluded specifically.)
In addition to that, some programs that are regularly used to assess
disk usage fail to realize that those are hard-links, and heavily
overcount disk usage. Most notably, this was the case with Windows
Explorer up until the last couple of Windows 10 versions. See e.g.
https://github.com/msysgit/msysgit/issues/58.
To save on the time needed to hard-link these dashed commands, with the
plan to eventually stop shipping with those hard-links on Windows, let's
introduce a Makefile knob to skip generating them.

There is a hard-coded list of `.pdb` files to copy. But we are about to
introduce the `SKIP_DASHED_BUILT_INS` knob in the `Makefile`, which
might make this hard-coded list incorrect.
Let's switch to a dynamically-generated list instead.

The implementation we moved from wt-status to enclose a pathname
that has a SP in it inside a dq-pair is a bit convoluted. It lets
quote_c_style_counted() do its escaping and then
(1) if the input string got escaped, which is checked by seeing if
the result begins with a double-quote, declare that we are
done. If there wasn't any SP in the input, that is OK, and if
there was, the result is quoted already so it is OK, too.
(2) if the input string did not get escaped, and the result has SP
in it, enclose the whole thing in a dq-pair ourselves.
Instead we can scan the path upfront to see if the input has SP in
it. If so, we tell quote_c_style_counted() not to enclose its
output in a dq-pair, and we add a dq-pair ourselves. Whether the
input had bytes that quote_c_style_counted() uses backslash quoting,
this would give us a desired quoted string. If the input does not
have SP in it, we just let quote_c_style_counted() do its thing as
usual, which would enclose the result in a dq-pair only when needed.

Some code in wt-status.c special case a path with SP in it, which
usually does not have to be c-quoted, and ensure that such a path

"git status" has trouble showing where it came from by interpreting
reflog entries that recordcertain events, e.g. "checkout @{u}", and
gives a hard/fatal error. Even though it inherently is impossible
to give a correct answer because the reflog entries lose some
information (e.g. "@{u}" does not record what branch the user was
on hence which branch 'the upstream' needs to be computed, and even
if the record were available, the relationship between branches may
have changed), at least hide the error to allow "status" show its
output.

The maintainer's dist rules are used to produce distribution
tarballs. They use "$(TAR) cf" and "$(TAR) rf" to produce archives
out of a freshly created local installation area, which means that
the built product can be affected by maintainer's umask and other
local environment.
Implementations of "tar" have ways (implementation specific,
unfortunately) to force permission bits and other stuff to allow the
user to hide these effects coming from the local environment. Teach
our Makefile to allow the maintainer to tweak the invocation of the
$(TAR) commands by setting TAR_DIST_EXTRA_OPTS.

We have had parallel implementations of "add -i/-p" since 2.25 and
have been using them from various codepaths since 2.26 days, but
never made the built-in version the default.
We have found and fixed a handful of corner case bugs in the
built-in version, and it may be a good time to start switching over
the user base from the scripted version to the built-in version.
