That's probably the bug/discussion I'm thinking of :-)

Right, with a prefix you could even (in theory) do some kind of tree
thingy instead of a linear search, too.

I'm sure there's a sufficiently-complex way to do a tree thingy for
globs, but I don't feel like coding it ;-)

And yes "tree thingy" is the official CS term :-P
