Given the experience Dieter had with one file where changes shouldn't
have had any affect but did, perhaps we can leave choicesin but replace
the body with remove.

But I note that choicesin and remove are not exactly the same. 
(choicesin 1 (list 1 2 3)) returns a list which is EQ to the CDR of the
second arg.  REMOVE doesn't, at least on cmucl.  Don't know if that
matters or not.
