At least `' seems to work for single quotes, which is quite
nice. I'd hate to have to type \(oq and \(cq! Interesting, I
hadn't thought of this concept as related to ligatures, but,
of course, it is the same thing as far as groff is

I like this idea, but definitely not trivial!

I agree, both \[--] and \[em] are infinitely better than
\(em, but -- (or ---) is best ;-)
