Hm, it's present in dash and bash, anyway.

Right, it's a minor case, if someone decides to remove /etc/X11/Xresources/x11-common. But I still think it's a tad less likely to be true than the existence of xrdb. > And then the reordering means you're looking for it twice (granted, > with 'type' the shell can cache the result of the first lookup, but > still). Hm, I don't understand? The second type is only done if [ -f "$USRRESOURCES" ], and ~/.Xresources should exist pretty seldomly these days?
