May I ask the less maintainers to comment this? Using various fonts
with xterm, I get various results. Sometimes, it appears as if an
underlined underscore is shown, sometimes not. What exactly is the
expected behaviour? It seems to me that many X fonts are broken (at
least those which come with XFree86 3.3.6) or don't behave
consistently w.r.t. this problem.
BTW, `xterm -version' gives
XFree86 4.0(129)
