Package: Emacs
Version: 23.0.60

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

After I do

% xrdb -remove
% src/emacs -Q --eval '(customize-face (quote default))'

I seem to be unable to select my beloved
"-misc-fixed-medium-r-semicondensed--13-*-*-*-*-*-*-*".  If I set
family=fixed, foundry=misc, width=semicondensed, height=100,
I get -misc-fixed-medium-r-normal--13-120-75-75-c-70-iso8859-1;
It appears that the "semicondensed" part is ignored.

I found the problem: in internal-set-lisp-face-attribute, we do the
following:

  if (prop_index)
    /* If a font-related attribute other than QCfont and QCfontset
       is specified, and if the original QCfont attribute has a font
       (font-spec or font-object), set the corresponding property in
       the font to nil so that the font selector doesn't think that
       the attribute is mandatory.  */
    font_clear_prop (XVECTOR (lface)->contents, prop_index);

The FONT_AVGWIDTH_INDEX entry also needs to be cleared out at this time,
otherwise the font backend won't find the semicondensed font.  I've
checked in a fix.
