Re: recent emacs font problems?

Hello.

I found out why changing font isn't working.  This change did it:

@@ -6603,7 +6604,9 @@
       frame_font = Fassq (Qfont, f->param_alist);
       xassert (CONSP (frame_font) && STRINGP (XCDR (frame_font)));
       frame_font = XCDR (frame_font);
-      set_lface_from_font_name (f, lface, frame_font, 1, 1);
+      /* Specify 0 for FORCE_P here, so that we don't override
+        a :family attribute specified for `default' for new frames.  */
+      set_lface_from_font_name (f, lface, frame_font, 0, 1);
     }
 #endif /* HAVE_WINDOW_SYSTEM */

        * xfaces.c (Finternal_set_lisp_face_attribute): Handle Qunspecified
        as value for QCfont attribute.
        (realize_default_face): lface should already exist; crash if not.
        Specify 0 for FORCE_P when calling set_lface_from_font_name.


The problem is that if FORCE_P is 0, all other attributes of the font won't be 
set unless they are unspecified in the default face.  For exampel size.  So if 
you have a default face font which is fully specified (no undefined parts) no 
font change will happen.

I cant really grasp the problem that lead to this change from the comment 
above, so if anyone can describe a case for the original problem, I can try and 
make this work.
