'less -R' has been mentioned. The reason for this, I suspect, is an
upstream change in groff, which the maintainer of the mutt package could
work around if he wished by setting GROFF_NO_SGR=1 in the environment
during the relevant part of the package build.
I've arranged for that upstream change not to affect man pages unless
you explicitly ask for it (using GROFF_SGR=1), but it turns out to be
quite hard to do that for groff in general. FreeBSD seem to have managed
it, so I'll have to look into their changes at some point.
