bug#2891: 23.0.92; 'Save Options' does not save font setting

[Leo]

I customise the font in Emacs.app by using ns-popup-font-panel and then
Menu > Options > Save Options. I check the custom file to find the no
options related to font are saved. I seem mto recall that font setting
is supposed to be saved.
