I don't want to apply this patch because it slows down a critical path.

Instead, could we maybe just simplify the canonicalization of msdos
filenames? Simplify it enough that name_translate_char() would be
sufficient? The rules would be:

- no suffix -> no dot
- basename > 8 characters -> can't happen
- forget about hidden files and the prepending '.'

None of the above rules are very fascistic - they'd simplify things a lot,
and I think the old logic is too complex to be really worth maintaining.
