Not really. This is a path canonicalization issue, which we know about.

I agree with Bill here, path canonicalization should take care of that, too.

There'a a potential problem if somebody does a case-only rename (not svn mv!) on
a file in the WC, because it wouldn't match the record in .svn/entries. But I
think a "don't do that" in the docs is a sufficient fix for 1.0.

Regarding trailing dots: interestingly enough, you can _not_ create a file with
a trailing dot in the name on Windows, even programatically. However, you _can_
stst("foo.") -- or "foo.." or "foo................" -- and get info about "foo",
so I suspect correct canonicalization would deal with that, too.
