To generalize this, it would be nice to have a command akin to the "which"
command in Unix that would return the full pathname of the file that would be
loaded were you to execute the load command.  E.g., (where-is-file "rmail")
might return "/usr/local/lib/emacs/lisp/rmail.elc", or nil if the file wasn't
found in the load-path.
