Actually, stows looks in the whole target dir for files linking to the
package you're unstowing, so it can detect when a directory is left with
only links to another package after removing some links, and change that
directory to a link to the package's directory. It can alos remove empty
directories left by removing links.

That's the alternative, "fast" unstowing that we plan on adding. But
with this behavior you can leave empty directories and directories full
of links to a single package, since you can't detect them. If you feel
like coding it, you're welcome :)
