Haha, sure sure, _getting_ that stat data in the first place is the
expensive part on Windows. However, that's something you _have_ to do no
matter what, so there's no way around that.
Turns out that it wasn't as bad as i thought. If you have
filetime_to_time_t() just return, say 116444736, I see
git add . improve with ~0.5 sec for 100K files
and git status improve with 0.05 sec
Surely, avoiding the tripple stat'ing in 'git status' would help a lot
more ;-) So, I guess we'll just leave the timestamp conversion as is,
and avoid complicating the index.
