Contrary to what its info entry says, process-status does not work if
its argument is a buffer name; in emacs -Q, evaluating the form:

   (let* ((buffer "bc-buf")
          (bc (start-process "bc" buffer "/usr/bin/bc")))
     (mapcar 'process-status (list buffer (get-buffer buffer))))

yields:

     (nil run)

The following patch fixes this problem for me:

2008-10-25  Markus Triska  <markus.triska@gmx.at>

        * process.c (Fprocess_status): Accept buffer names.
        Update docstring to match info description.

Yes, we can't accept buffer names in process-status because it already
treats strings as process names.

I've updated the lisp manual.  Thanks for spotting this.
