I seem to remember that on some systems "more" is the name of the
full-featured pager that knows how to scroll forward and backward and
handle color.  (My memory could be faulty.  A search in the makefile
for DEFAULT_PAGER=more only finds AIX, which is not the platform I was
thinking of.)

On a stock Debian system "more" is especially primitive, which means
that it passes colors through, too.  It being so primitive also means
it is not a particularly good choice for the PAGER setting, though,
so probably that's not too important.

Hope that helps,
Jonathan
