Creating '_' in S/R modes

Yes, in looking through the source code I saw the C-q _ solution.  I would
still prefer for "_" "_" to get translated to "_" so that I don't have to
hit another control sequence.  For one thing, it would be a lot easier to
explain (and remember) for newbies.

BTW, this is in light of the current discussion on R-help about 'disabling'
'_' as an assignment character to ease compatibility with (most) languages
that consider '_' a valid character in identifiers.
