Thanks for your reply Thomas, but I'm afraid I'm not following what you say
here. I'm not not very familiar with fonts so I'm confused by your comment "if
the font-metrics say it's that wide".

Note that I've been using the same xinitrc, Xdefaults, and ctwmrc files since
the mid '90s and have never had this behavior.

Is there some way that I could revert that change or configure xterm to
not use it?

Thanks again,
