What I meant but didn't say was that arch supports it fully when using
explicit and taglines (and of course implicit which is a combination of
the two). Its when you get into names based that you start to have a
problem.

Arch does, and gives you two ways to do it: 

1. You can use explicit tagging.
2. You can use taglines.

So hack up the names based method to support .arch-ids for just directories. :)

However, that would only work when moving directories. If you move a file
between directories, then they would still be an add/remove pair. Why that
is necessary should be obvious.

Good luck and happy holidays!
