The reason why we did not start with the main loop to begin with is that
it is the first user of `list_and_choose()`, which uses the `list()`
function that we conveniently introduced for use by the `status`
command.
Apart from the "and choose" part, there are more differences between the
way the `status` command calls the `list_and_choose()` function in the
Perl version of `git add -i` compared to the other callers of said
function. The most important ones:
- The list is not only shown, but the user is also asked to make a
choice, possibly selecting multiple entries.
- The list of items is prefixed with a marker indicating what items have
been selected, if multi-selection is allowed.
- Initially, for each item a unique prefix (if there exists any within
the given parameters) is determined, and shown in the list, and
accepted as a shortcut for the selection.
These features will be implemented later, except the part where the user
can choose a command. At this stage, though, the built-in `git add -i`
still only supports the `status` command, with the remaining commands to
follow over the course of the next commits.
In addition, we also modify `list()` to support displaying the commands
in columns, even if there is currently only one.
The Perl script `git-add--interactive.perl` mixed the purposes of the
"list" and the "and choose" part into the same function. In the C
version, we will keep them separate instead, calling the `list()`
function from the `list_and_choose()` function.
Note that we only have a prompt ending in a single ">" at this stage;
later commits will add commands that display a double ">>" to indicate
that the user is in a different loop than the main one.

For simplicity, we only implemented the `status` command without colors.
This patch starts adding color, matching what the Perl script
`git-add--interactive.perl` does.

This is what the Perl version does, and therefore it is what the
built-in version should do, too.

This implements the `status` command of `git add -i`. The data
structures introduced in this commit will be extended as needed later.
At this point, we re-implement only part of the `list_and_choose()`
function of the Perl script `git-add--interactive.perl` and call it
`list()`. It does not yet color anything, or do columns, or allow user
input.
Over the course of the next commits, we will introduce a
`list_and_choose()` function that uses `list()` to display the list of
options and let the user choose one or more of the displayed items. This
will be used to implement the main loop of the built-in `git add -i`, at
which point the new `status` command can actually be used.
Note that we pass the list of items as a `struct item **` as opposed to
a `struct item *`, to allow for the actual items to contain much more
information than merely the name.

Make the diffstat interface (namely, the diffstat_t struct and
compute_diffstat) no longer be internal to diff.c and allow it to be used
by other parts of git.
This is helpful for code that may want to easily extract information
from files using the diff machinery, while flushing it differently from
how the show_* functions used by diff_flush() do it. One example is the
builtin implementation of git-add--interactive's status.

This is hardly the first conversion of a Git command that is implemented
as a script to a built-in. So far, the most successful strategy for such
conversions has been to add a built-in helper and call that for more and
more functionality from the script, as more and more parts are
converted.
With the interactive add, we choose a different strategy. The sole
reason for this is that on Windows (where such a conversion has the most
benefits in terms of speed and robustness) we face the very specific
problem that a `system()` call in Perl seems to close `stdin` in the
parent process when the spawned process consumes even one character from
`stdin`. And that just does not work for us here, as it would stop the
main loop as soon as any interactive command was performed by the
helper. Which is almost all of the commands in `git add -i`.
It is almost as if Perl told us once again that it does not want us to
use it on Windows.
Instead, we follow the opposite route where we start with a bare-bones
version of the built-in interactive add, guarded by the new
`add.interactive.useBuiltin` config variable, and then add more and more
functionality to it, until it is feature complete.
At this point, the built-in version of `git add -i` only states that it
cannot do anything yet ;-)

Inspired by 21416f0a07 ("restore: fix typo in docs", 2019-08-03), I ran
"git grep -E '(\b[a-zA-Z]+) \1\b' -- Documentation/" to find other cases
where words were duplicated, e.g. "the the", and in most cases removed
one of the repeated words.
There were many false positives by this grep command, including
deliberate repeated words like "really really" or valid uses of "that
that" which I left alone, of course.
I also did not correct any of the legitimate, accidentally repeated
words in old RelNotes.

When updating the skip-worktree bits in the index to align with new
values in a sparse-checkout file, Git scans the entire working
directory with lstat() calls. In a sparse-checkout, many of these
lstat() calls are for paths that do not exist.
Enable the fscache feature during this scan.
In a local test of a repo with ~2.2 million paths, updating the index
with `git read-tree -m -u HEAD` with a sparse-checkout file containing
only `/.gitattributes` improved from 2-3 minutes to 15-20 seconds.
More work could be done to stop running lstat() calls when recursing
into directories that are known to not exist.
This brings substantial wins in performance because the FSCache is now
per-thread, being merged to the primary thread only at the end, so we do
not have to lock (except while merging).
