Yep. Now give me an easy way to rename them all so that the glob *.mid
will produce them in the right order. BTW, there's no guarantee that
the files have no gaps; some other directories have things like
Iol_08_11.mid being followed by Iol_12.mid - I'd rather not renumber
them based on their indices in the final list.

But like I said, it's an unusual case.
