So you're proposing that the "pattern" argument is passed directly to
FindFirstFile as the wildcard on Windows, and to Python's fnmatch on
Linux? That's not terrible, but there is the "my program deleted files
it shouldn't have" problem for edge cases.

Isn't fnmatch's behaviour quite well defined? I think if it's not too
difficult it'd be better to mimic that (emulating "bad patterns" using
fnmatch where necessary on Windows).
