Re: [groff] modernize -T ascii rendering of opening single quote

[Doug McIlroy]

Ingo has recorded me as being opposed to rendering \(oq and \(cq
the same in -T ascii.

I had raised the issue of ` in m4 and shell scripts. However, it
is good practice to make examples by pasting in working code,
which can in turn be cut, especially from nroff-ed documents.

The rendering of \(oq is irrelevant to this practice.

For publishing m4 programs, however, it is really nice
to have symmetrical left and right quotes. On asking around
(and also in some of my own work), I find that people are
very likely to use "changequote" to bracketing pairs such
as {} [] <> and not to risk damaging the code by transliteration

I conclude that my concern is very iffy. It should not be
taken as a "no" vote.
