I looked into the problem some more, and it's a problem with "kterm".
Apparently kterm 6.2.0 doesn't support escape sequences like "ESC [ 2
4 m".  It works OK with xterm.  Unfortunately we use kterm a lot
around here, since we have to deal with Kanji, so asking people to use
xterm is a non-starter.  Anyway, perhaps you should mention in the
groff and/or less documentation that "less -R" does not work with
kterm so people who want Japanese support have to avoid this solution.
