As it stands, all categories would show.  The workaround could be 
removed, however, since it is no longer needed in 2,1.

We could have hide empty only show cats that are empty for both posts 
and links.  If there is a link count but no post count, it won't be 
listed.  If someone wants to create a patch for that we can try it out.
