Sorry, I've lost context, but yes it'd be OK if Bison's quoting
style depended on whether the LC_CTYPE locale was "C" or not.

Sure, if you want to be that fancy, you can use double-quotes
if the token contains a single quote.  But what would happen
if the token contains both single and double quotes?  Would
we fall back on \ in that case, e.g.:

   missing '"\'"' at end of file

if the actual token is:

   "'"

?
