  Okay, I wrote it, so I guess I'll respond to this one...  Here are
the two situations (eatme, eatme2, and eatme.again are all directories):

	mv /ram5/eatme /ram5/eatme2

  If eatme2 doesn't exist, the directory eatme gets renamed to eatme2
(ie: eatme2 is the exact same directory tree as eatme, but with a
different name).

	mv /ram5/eatme /ram5/eatme.again

  If eatme.again DOES exist, then the directory tree 'eatme' is moved
into the directory 'eatme.again', not given the name 'eatme.again'.

  What actually happens, is that a ChangePathGS is called.  That
should work fine...  Does for me...

  Well, in my copy, it works perfectly.

  Jawaid:  have you modified the source code and recompiled for the
GNO distribution?  If so, could you mail me the latest set of sources
so I can see if this is a bug that was introduced after I gave you the
source?

  Don't bother.  If it really is a bug (which it isn't in mine), I'll
fix it as soon as I get the latest code from Jawaid.
