I know about the overriding, and I'm sorry for not making myself clear
about that (somehow, I thought it was obvious).  My problem was not
with the technical aspects, but with human aspects.  Like this, for
example:

>  (gdb) pr

Exactly!  Right now, if I forget that I'm not debugging Emacs (yes, it
happens ;-) and type "pr" out of habit, I get the above response, or
something similar.  With the proposed alias, I might get the
`previous' command actually _executed_, to my surprise and annoyance.

Another problem is that I will lose the alias when I'm debugging
Emacs.  Not good, IMO.
