Bill Wohler c90c4cf168 * mh-acros.el (mh-defun-compat): Rename to defun-mh in order that

find-func (invoked by clicking on the filename link in the *Help*
buffer.
(mh-defmacro-compat): Rename to defmacro-mh. Ditto. *
mh-e.el: (mh-defgroup): Rename to defgroup-mh. Ditto.
(mh-defcustom): Rename to defcustom-mh. Ditto.
(mh-defface): Rename to defface-mh. Ditto.
(mh-font-lock-add-keywords): Make changes according to these
renamings.
