Nice!  It doesn't quite work for me because I set both "font" and
"boldFont" in my resources.  I see in urxvt(7)

    Ps = 710   Set normal fontset to Pt. Same as Ps = 50.
    Ps = 711   Set bold fontset to Pt. Similar to Ps = 50

However I'm not sure how this should be integrated into the
|-separated fontlist you created.  Ideas?

Thanks,
Aron
