While this was a minor request I can empathise that one would like to
avoid cluttering up an implementation with dynamic variables (I don't
think speed of function redefinition is an issue because the
*warn-on-redefinition* predicate is EQ and not even tested when WHAT is
usually NIL).

It has only taken me a few minutes to replace the use of SHORT-SITE-NAME
in my code with a new function called HOSTNAME.

It is great learning the beginnings of how to modify CLISP and beginning
to understand what it means to implement Lisp in C instead of Lisp in
Lisp.
