Xresource pane.menubar.*font no longer takes effect

[Glenn Morris]

In the 22 branch, and in the trunk prior to the unicode merge (I
think, of the order a week or so), I can change the menubar font with
an X resource. This no longer works.

This is in a build --with-x-toolkit=athena --without-toolkit-scroll-bars.

This used to work:

./src/emacs -Q --xrm 'Emacs.pane.menubar.*font: 
-adobe-helvetica-medium-r-normal-*-24-*-*-*-*-*-iso8859-1'

Now it has no effect.
