Ah yes, now I recall: the idea was to flip the meaning of ARG in
exchange-point-and-mark, yes?  This is not a bad idea in principle.  But
the effects may be strange.  It would mean that, when the mark is
active, you need to do C-u C-x C-x to exchange point and mark without
deactivating the mark, which is inconvenient.  So this may need
tweaking.

For this change, please post your proposed change as a patch to
emacs-devel, for others to comment, instead of checking it in directly.
