In preparation for re-implementing `git add -p` in pure C (where we will
purposefully keep the implementation of `git add -p` separate from the
implementation of `git add -i`), let's verify that the user is told the
same things as in the Perl version when the diff file is either empty or
contains only entries about binary files.

The `git add -p` command offers different prompts for regular diff hunks
vs mode change pseudo hunks vs diffs deleting files.
Let's cover this in the regresion test suite, in preparation for
re-implementing `git add -p` in C.
For the mode change prompt, we use a trick that lets this test case pass
even on systems without executable bit, i.e. where `core.filemode =
false` (such as Windows): we first add the file to the index with `git
add --chmod=+x`, and then call `git add -p` with `core.filemode` forced
to `true`. The file on disk has no executable bit set, therefore we will
see a mode change.

The TTY prerequisite is a rather heavy one: it not only requires Perl to
work, but also the IO/Pty.pm module (with native support, and it
requires pseudo terminals, too).
In particular, test cases marked with the TTY prerequisite would be
skipped in Git for Windows' SDK.
In the case of `git add -p`, we do not actually need that big a hammer,
as we do not want to test any functionality that requires a pseudo
terminal; all we want is for the interactive add command to use color,
even when being called from within the test suite.
And we found exactly such a trick earlier already: when we added a test
case to verify that the main loop of `git add -i` is colored
appropriately. Let's use that trick instead of the TTY prerequisite.
While at it, we avoid the pipes, as we do not want a SIGPIPE to break
the regression test cases (which will be much more likely when we do not
run everything through Perl because that is inherently slower).

In this developer's workflows, it often happens that a hunk needs to be
edited in a way that adds lines, and sometimes even reduces the number
of context lines.
Let's add a regression test for this.
Note that just like the preceding test case, the new test case is *not*
handled gracefully by the current `git add -p`. It will be handled
correctly by the upcoming built-in `git add -p`, though.

These patches fix several bugs in quoting arguments when spawning shell
scripts on Windows.
Note: these bugs are Windows-only, as we have to construct a command
line for the process-to-spawn, unlike Linux/macOS, where `execv()`
accepts an already-split command line.
Furthermore, these fixes were not included in the CVE-2019-1350 part of
v2.14.6 because the Windows-specific quoting when spawning shell scripts
was contributed from Git for Windows into Git only in the v2.21.x era.

When constructing command-lines to spawn processes, it is an unfortunate
but necessary decision to quote arguments differently: MSYS2 has
different dequoting rules (inherited from Cygwin) than the rest of
Windows.
To accommodate that, Git's Windows compatibility layer has two separate
quoting helpers, one for MSYS2 (which it uses exclusively when spawning
`sh`) and the other for regular Windows executables.
The MSYS2 one had an unfortunate bug where a `,` somehow slipped in,
instead of the `;`. As a consequence, empty arguments would not be
enclosed in a pair of double quotes, but the closing double quote was
skipped.
Let's fix this.

At the point where `mingw_spawn_fd()` is called, we already have a full
path to the script interpreter in that scenario, and we pass it in as
the executable to run, while the `argv` reflect what the script should

In v2.20.x, Git clones submodules recursively by first creating the
submodules' gitdirs and _then_ "updating" the submodules. This can lead
to the situation where the clone path is taken because the directory
(while it exists already) is not a git directory, but then the clone
fails because that gitdir is unexpectedly already a directory.
This _also_ works around the vulnerability that was fixed in "Disallow
dubiously-nested submodule git directories", but it produces a different
error message than the one expected by the test case, therefore we
adjust the test case accordingly.
Note: as the two submodules "race each other", there are actually two
possible error messages, therefore we have to teach the test case to
expect _two_ possible (and good) outcomes in addition to the one it
expected before.
Note: this workaround is only necessary for the v2.20.x release train;
The behavior changed again in v2.21.x so that the original test case's
expectations are met again.

This allows hosting providers to detect whether they are being used
to attack users using malicious 'update = !command' settings in
.gitmodules.
Since ac1fbbda2013 (submodule: do not copy unknown update mode from
.gitmodules, 2013-12-02), in normal cases such settings have been
treated as 'update = none', so forbidding them should not produce any
collateral damage to legitimate uses. A quick search does not reveal
any repositories making use of this construct, either.

Since ac1fbbda2013 (submodule: do not copy unknown update mode from
.gitmodules, 2013-12-02), Git has been careful to avoid copying
[submodule "foo"]
update = !run an arbitrary scary command
from .gitmodules to a repository's local config, copying in the
setting 'update = none' instead. The gitmodules(5) manpage documents
the intention:
The !command form is intentionally ignored here for security
reasons
Unfortunately, starting with v2.20.0-rc0 (which integrated ee69b2a9
(submodule--helper: introduce new update-module-mode helper,
2018-08-13, first released in v2.20.0-rc0)), there are scenarios where
we *don't* ignore it: if the config store contains no
submodule.foo.update setting, the submodule-config API falls back to
reading .gitmodules and the repository-supplied !command gets run
after all.
This was part of a general change over time in submodule support to
read more directly from .gitmodules, since unlike .git/config it
allows a project to change values between branches and over time
(while still allowing .git/config to override things). But it was
never intended to apply to this kind of dangerous configuration.
The behavior change was not advertised in ee69b2a9's commit message
and was missed in review.
Let's take the opportunity to make the protection more robust, even in
Git versions that are technically not affected: instead of quietly
converting 'update = !command' to 'update = none', noisily treat it as
an error. Allowing the setting but treating it as meaning something
else was just confusing; users are better served by seeing the error
sooner. Forbidding the construct makes the semantics simpler and
means we can check for it in fsck (in a separate patch).
As a result, the submodule-config API cannot read this value from
.gitmodules under any circumstance, and we can declare with confidence
For security reasons, the '!command' form is not accepted
here.
