I found nice to know if the alias is an user alias or an Emacs one,
and to see in which file is defined.
Below a new patch that solves the issue about showing the filename
where the alias is defined.  This patch does not interfere with
the Stefan commit mentioned in this thread.

Subject: [PATCH] Show the filename where an alias is defined

* help-fns (describe-function-1): Pass 'defun as TYPE
to 'find-lisp-object-file-name' when OBJECT
is an alias (Bug#21950).
