less should work no matter what.  What I just saw in quick tests is that
less complains in a situation where the value of TERM doesn't lead to a
set of reasonable capabilities:

garrett at thinkpad{14}> env TERM=bogus /tmp/more /etc/release
WARNING: terminal is not fully functional
/etc/release  (press RETURN)

Once you press RETURN, it works.  One could argue that in "more" mode,
less shouldn't have that complaint.  If one specifies "-d", it won't
give it.  We could make that change in a local version. :-)
