Although the quotes that we want to curl are paired, there are other stray grave 
accents and apostrophes that we shouldn't curl.

Are you sure?  The first grave accent looks like a quasiquote, so there 
shouldn't be a closing apostrophe.  Those commas are clues that it's a quasiquote.

Here's my current draft regexp to catch the quotations we want to curl:

  `\\([^[:space:]'`‘’][^'`‘’]*\\)?'

A bit tricky, but could be worse.  Newlines are allowed, as some doc strings 
break these quotes across line boundaries (e.g., info node references).
