Comment 145 for bug 106737

It does fit in quite nicely with what I've been looking at with the EmptyTrash() implementation, so I'm happy to look at it (and in fact, I just spent a couple of hours poking through the code from where Jorg left off - I'll write up my thoughts).

I can run a profile off a vfat filesystem (usb stick or loopback trickery) for case-insensitive filenames, I should be able to hit the same issues as on Windows.

There is an issue even on Linux: if I rename an imap folder "aaa" -> "Aaa", it looks fine in the GUI, but the old "aaa" directory will still be on the filesystem. So something isn't quite right there.
