I agree that's a problem, but it has nothing to do with Subversion. If
there were no revision control in the loop, the exact same problem would

Anyway, under the scheme I was talking about, you'd still have no
problem. When Susie asks to check in Foo.htm, Subversion sees that she's
on a case-insensitive filesystem and updates "foo.htm" instead, and
things still work under Unix just fine.

I think its more accurate to say "Windows is a case-agnostic file
system." Sure, filesystem file updates generally won't change the
filesystem's casing of the filename, but the operational reality is that
very few tools care. Any tool that caches a filename in some kind of
config file on Windows expects that the casing is not significant. This
includes many of the OS vendor's own tools. VisualStudio for one. Yeah,
you could try to claim this is just another "bug" in VisualStudio, but
it won't really help me any. I still have to get it to work, and it
works just fine when VisualStudio is talking to VSS. Its only Subversion
that has a problem.

That doesn't even help for working copies, as the file's parent
directory's casing can be an issue too. Windows also doesn't care if I
call my base hard drive "C:\" or "c:\".
