At this stage on the journey to a fully built-in git add, we already have
everything we need, including the --interactive and --patch options, as long
as the add.interactive.useBuiltin setting is set to true. This config
setting is kind of a feature flag that is currently turned off by default,
and will be for a while, until we get confident enough that the built-in
version does the job, and retire the Perl script.

Except for a few things that are all minor I already mentioned, and
that I'd need to think a bit more to form an opinion on 6/7 and 7/7,
they all looked quite straight-forward.

Will queue.
