23.0.60; fontconfig font names

[David Hansen <david.hansen@gmx.net>]

Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the emacs-pretest-bug@gnu.org mailing list.

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

Hello,

Emacs doesn't handle fontconfig font names right, e.g.

emacs -fn "DejaVu Sans Mono:embolden=true:rgba=none:antialias=false"

all extra parameters are ignored.

`font-spec' parses the string right, but it seems the information is
lost in `list-fonts'.  Besides Emacs uses antialiased (and no subpixel
rendering) fonts no matter what I put in my ~/.fonts.conf.  Well, I
don't quite understand this cryptic file but `xterm -fa "..."' is doing
what I expect (with the attached fonts.conf file I get subpixel
rendering in a xterm but not in Emacs).

David
