suffix removal again

suffix removal again

[Zefram]

-----BEGIN PGP SIGNED MESSAGE-----

Even after my previous two patches on the subject, there is still one
remaining bug in suffix removal, that has taken me a while to reproduce.
The symptom is that when menu completing parameter names (after a $),
inserting space or a character such as `:' (that must go immediately
after the parameter name) causes the last character of the parameter
name to be deleted.  What is happening is that zsh is attempting to
delete the space it added following the parameter name, not realising
that it already deleted that for the purpose of menu completion.

This patch must be applied on top of the others.  If anyone notices any
further problems in this area, please let me know.
