 + fix phantom untracked files when core.ignorecase is set

I didn't see any comment on the original patch, so I assume you're OK
with the few extra bytes added to each cache entry? Otherwise, I can try
to retool it to keep the directory entries in a separate hash, so only
case-insensitive people pay the extra price.

I did a few trivial timings, and the extra bytes didn't seem to make any
difference.

I tend to agree with you that 8 extra bytes per cache entry wouldn't hurt.
I also suspected that the cost of code complexity coming from both
maintaining and conditionally looking up a separate hash would outweigh
the benefit.
