I added some more default subdirs:

I ran different greps on the whole tree to ensure that no existing
port will invoke the magic. Well, there were 3 ports with runaway
backslashes that would, but they're fixed now. So I guess I'll be
committing this in a day or two if I don't get shot before that. And
since this doesn't affect you by default, I'll take another day or two
to document it.
