[Fontconfig] Question about disabling globaladvance

[Peng Deng]

Recently I started to use a monospaced font called "Monaco".  However,
this font would be wrongly rendered with extra letter spacing if
globaladvance is not turned "false" in fonts.conf.

But the problem is, not every application uses fonts.conf for their
fonts, like the emacs23 (with Xft support) which reads Xft settings
from ~/.Xresources.  So is there anyone who knows how to disable
globaladvance with ~/.Xresources for these apps?

Thanks in advance for any hint.
