Rewrite of "git add -i" in C that appeared in Git 2.25 didn't

has become the default in the latest release.
The test worked despite the error, because even though
test_file_is_empty is a non-existent function, the '!' negated the
return value and made it pass. It'd be better to avoid the negation,
so something like
test_file_not_empty actual

number of lines of expected output to make the test a bit tighter.

vscode: improve tab size and wrapping
The contrib/vscode/init.sh script initializes the .vscode directory with
some helpful metadata so VS Code handles Git code better.
One big issue that VS Code has is detecting the tab width based on file
type. ".txt" files were not covered by this script before, so add them
with the appropriate tab widths. This prevents inserting spaces instead
of tabs and keeps the tab width to eight instead of four or two.
While we are here, remove the "editor.wordWrap" settings. The editor's
word wrap is only cosmetic: it does not actually insert newlines when
your typing goes over the column limit. This can make it appear like you
have properly wrapped code, but it is incorrect. Further, existing code
that is over the column limit is wrapped even if your editor window is
wider than the limit. This can make reading such code more difficult.
Without these lines, VS Code renders the lines accurately, without
"ghost" newlines.

setup: tighten ownership checks post CVE-2022-24765
8959555cee7 (setup_git_directory(): add an owner check for the top-level
directory, 2022-03-02), adds a function to check for ownership of
repositories using a directory that is representative of it, and ways to
add exempt a specific repository from said check if needed, but that
check didn't account for owership of the gitdir, or (when used) the
gitfile that points to that gitdir.
An attacker could create a git repository in a directory that they can
write into but that is owned by the victim to work around the fix that
was introduced with CVE-2022-24765 to potentially run code as the
victim.
An example that could result in privilege escalation to root in *NIX would
be to set a repository in a shared tmp directory by doing (for example):
$ git -C /tmp init
To avoid that, extend the ensure_valid_ownership function to be able to
check for all three paths.
This will have the side effect of tripling the number of stat() calls
when a repository is detected, but the effect is expected to be likely
minimal, as it is done only once during the directory walk in which Git
looks for a repository.
Additionally make sure to resolve the gitfile (if one was used) to find
the relevant gitdir for checking.
While at it change the message printed on failure so it is clear we are
referring to the repository by its worktree (or gitdir if it is bare) and
not to a specific directory.

revisions.txt: escape "..." to avoid asciidoc horizontal ellipsis
In asciidoc's HTML output of the "gitrevisions" and "git-rev-parse"
documentation, the header:
The ... (three-dot) Symmetric Difference Notation
is rendered using "&8230;", a horizontal ellipsis. This is visually
ugly, but also hard to search for or cut-and-paste. We really mean three
ascii dots (0x2e) here, so let's make sure it renders as such.
The simplest way to do that is just escaping the leading dot, as the
instances in the rest of the section do. Arguably this should all be
converted to use backticks, which would let us drop the quoting here and
elsewhere (e.g., {carat}). But that does change the rendering slightly.
So let's fix the bug first, and we can decide on migrating the whole
section separately.
Note that this produces an empty doc-diff of the manpages. Curiously,
asciidoc produces the same ellipsis entity in the XML file, but docbook
then converts it back into three literal dots for the roff output! So
the roff manpages have been correct all along (which may be a reason
nobody noticed this until now).

bug_fl(): correctly initialize trace2 va_list
The code added 0cc05b044f (usage.c: add a non-fatal bug() function to go
with BUG(), 2022-06-02) sets up two va_list variables: one to output to
stderr, and one to trace2. But the order of initialization is wrong:
We copy the contents of "ap" into "cp" before it is initialized, meaning
it is full of garbage. The two should be swapped.
However, there's another bug, noticed by Johannes Schindelin: we forget
to call va_end() for the copy. So instead of just fixing the copy's
initialization, let's do two separate start/end pairs. This is allowed
by the standard, and we don't need to use copy here since we have access
to the original varargs. Matching the pairs with the calls makes it more
obvious that everything is being done correctly.
Note that we do call bug_fl() in the tests, but it didn't trigger this
problem because our format string doesn't have any placeholders. So even
though we were passing a garbage va_list through the stack, nobody ever
needed to look at it. We can easily adjust one of the trace2 tests to
trigger this, both for bug() and for BUG(). The latter isn't broken, but
it's nice to exercise both a bit more. Without the fix in this patch
(but with the test change), the bug() case causes a segfault.
