bug#1126: Xresources override face settings

[Stefan Monnier]

Package: Emacs
Version: 23.0.60

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

When I do 

% xrdb -remove
% echo 'Emacs.font: -misc-fixed-medium-r-semicondensed--13-*-*-*-*-*-*-*' | xrdb -load
% src/emacs -Q --eval '(customize-face (quote variable-pitch))'

I get a buffer that shows that `variable-pitch' should use a "Sans
Serif" family, yet C-u C-x = on the "sample" text shows that it's
actually
using -misc-fixed-medium-r-semicondensed--13-120-75-75-c-60-iso8859-1.
Apparently no amount of changing the `family' setting will change the
font used for that face.

The `variable-pitch' face is defined with `Sans Serif' as the family in
faces.el.  The font backend regards `Sans Serif' as a match for `fixed',
in accordance with face-font-family-alternatives.  I'm not sure what the
problem is; could you elaborate?

I do have "Sans Serif", it is normally mapped to Vera Bitstream, by
fontconfig, not to "fixed".  And if I change "Sans Serif" to something
else, it makes no difference, no matter what I type in that field.
I just figured that I can "fix" things by setting variable-pitch's
`width' to `medium' rather than to unset (which falls back on the
default face's `semicondensed').

Hmm, I forgot to actually check in the change.  Try again with latest
CVS?
