emacs-unicode-2 fontset bug

[Leon]

Dear all,

After many trials, I think I found another bug of emacs-unicode-2
branch. I have the following settings in ~/.Xresources:

,----[ ~/.Xresources ]
| Emacs.Fontset-0: -*-*-medium-r-*-*-16-*-*-*-*-*-fontset-unicode,\
| ascii:-*-terminus-medium-r-*-*-16-*-*-*-*-iso8859-1,\
| mule-unicode-2500-33ff:-gnu-unifont-medium-r-*-*-16-*-*-*-*-*-iso10646-1,\
| mule-unicode-e000-ffff:-gnu-unifont-medium-r-*-*-16-*-*-*-*-*-iso10646-1,\
| mule-unicode-0100-24ff:-gnu-unifont-medium-r-*-*-16-*-*-*-*-*-iso10646-1
| Emacs.Font: fontset-unicode
`----

In emacs-unicode-2, the font for ascii will be a font that matches 
"-*-*-medium-r-*-*-16-*-*-*-*-*" instead of
"-*-terminus-medium-r-*-*-16-*-*-*-*-iso8859-1".

However, emacs 21.3 will correctly pick up the font matches
"-*-terminus-medium-r-*-*-16-*-*-*-*-iso8859-1". 

Here is the output of describe-fontset in emacs 23 and 21.3:

fontset23.txt
Description: emacs23_fontset

fontset21.txt
Description: emacs21_fontset
