Interesting, that is probably because of the following snip from
lesspipe.sh (the gentoo less filter)

     # Only colorize if we know less will handle raw codes
             for opt in ${LESS} ; do
                     if [[ ${opt} == "-r" || ${opt} == "-R" ]] ; then
                             ${LESSCOLORIZER} "$1"
                             break
                     fi
             done

I would probably consider that a bug worth filing on b.g.o. That
snipplet assumes that options would be specified 1 per dash with no
ganging, which does not fit in the old unix-style paradigm; but it
also completely ignores the gnu-style options given in the man page
(--raw-control-chars and --RAW-CONTROL-CHARS for -r and -R
respectively)

You should approach relationships like chess. And preferably as Deep Blue plays
it, or at least as Kasparov.
