Really?  I thought the intention was so that you could define your own 
_rule_ (set of commands) for `clean', without losing the existing rule 
(since Make only allows one for each target).

Yes, this fixes this particular example, but I didn't think the user was 
supposed to know about/tamper with the local targets...  (Of course in the 
runtime directory it hardly matters since there are no Mercury source files.)
