Thank you for the input and the fixes.  They are all valid.

Accepted in full and will go out again in the next official
patch/release (if there is another one :-).

Ditto.

I can't install this in our sources.  After a long and drawn-out
design process, it was decided here at Athena that purge should be
*only* a purge, and should not take command-line arguments.  The
purpose of the purge command is to give our users a very simple
command they can type that they can be sure will get rid of the
deleted files in their home directory if they are over quota and need
to do something about it.

You can leave your patch in your version of the sources, but I can't
put it into ours.  It's a valid patch if it's the functionality you
want, but it's not what we want here :-)

P.S. Now, if you had submitted a man page patch for expunge and purge
as well, I might have thought about installing it :-)
