bug#1378: 23.0.60; Font selection does not respect emacs.font

[Nils Anders Danielsson <nad@Cs.Nott.AC.UK>]

When Emacs is started using

   emacs -Q --xrm 'emacs.font: 
-misc-fixed-medium-r-normal-*-15-140-75-75-c-90-iso10646-1' \
     --xrm 'emacs.fontBackend: xft,x'

and a file with Greek characters (αβγ) is displayed, some Xft font is
used for the Greek characters instead of my selected X font, even
though the X font contains glyphs for these characters. The X font is
used for many other characters, though, including some Unicode symbols
(like ∀⊢). If I start Emacs using

   emacs -Q --xrm 'emacs.font: 
-misc-fixed-medium-r-normal-*-15-140-75-75-c-90-iso10646-1' \
     --xrm 'emacs.fontBackend: x'

then the X font is used for all characters (naturally).

This seems to be a regression. I did not have this problem when I was
using a previous version of the emacs-snapshot package.
