I did an RFC-patch for that (that I mistakenly didn't sent as a reply to
this e-mail). And I believe that you're correct. My solution is inspired
of curl's strequal.

Is the reason for git not to care about lower/upper-case for beeing able
to support windows? Or is there any other smart reason?

I was also thinking about discarding files by looking at their
modification date. If the modification timestamp is older than/or equal to
the latest commit, there's probably no reason for examine that file any
further. I'm not sure about the side effects this may imply though. I
think they can be quite nasty. Is this something worth digging more in
or am I already on the wrong path?
