Hmmm... I have already found something interesting: my CentOS root file system 
lacks a /etc/X11/app-defaults/XTerm file and the Ubuntu one contains such a 
file, and contains a CharClass setting with a comment about double-clicking on 
a URL...  I'm guessing xterm's compiled in default is probably what I want (it 
is probably what I am used to from when I first used XTerms under DECWindows 
way back when).
