Well, I lied. I couldn't sleep, so here is a preview that seems to pass
all the test at least. It needs to be split into two, but I am too tired
to do that properly tonight.
The main part of the change is third hunk (preimage ll.258-) to the bottom
of builtin-add.c and follows the idea outlined in the message this is a
response to.
A private function add_files_to_cache() in builtin-add.c was borrowed by
checkout and commit re-implementors without getting properly refactored to
more library-ish place. This does the refactoring, and most of the
changes you see in the diffstat are this; it should come before the main
part of the change.
