It may well be the case that this lstat() returning success was caused by
a ghost match with a file with different case, and I think it is the right
thing to say "no, it does not exist" if that is the case.

I wonder what happens when the file with the same case does exist that we
are trying to make sure is missing?

As far as I can tell, icase_exists() does not ask "does a file with this
name in different case exist, and a file with this exact case doesn't?"
but asks "does a file with this name, or another name that is different
only in case, exist?".
