[Fontconfig] style preference in config

[Jeremy Huddleston]

I've run into a bit of a problem with Fontconfig.  I first noticed  
this while using firefox.  Some web pages' <pre> blocks would get  
rendered garbled.  I tracked this down to a simplified test case using  
pango-view:

$ pango-view --font="Fixed" /etc/passwd
# See garbled cruft in the view (see attached)

I think the main issue here is the fontconfig match problem:
$ fc-match Fixed
12x13ja.pcf.gz: "Fixed" "ja"

If I explicitly ask for the "Regular" style, I get an expected render:
$ fc-match Fixed:style=Regular
7x13.pcf.gz: "Fixed" "Regular"

$ pango-view --font="Fixed:Style=Regular" /etc/passwd
# See an expected render

It looks like we need some logic in the config file to prefer  
style=Regular if no style is designated.  Am I correct in that  
assumption?  If so, how do I do that?  If not, does anyone know what's  
going wrong here?

Thanks,
Jeremy
