"update VERS" does:

   tla undo VERS
   tla apply-delta `tla logs -f VERS | tail -1` `tla revisions -f VERS`
   tla redo

IOW, it updates the current tree with respect to VERS `underneath' any
changes between VERS and the current tree.  This formulation is
_incredibly_ useful (when you're dealing with a fork of VERS, this is
almost always what you want to do), and I find it `just makes sense.'
