If the code is using ‘...’ quotes, how can I grep to match quoted

You can use curved quotes in the grep pattern. I just now tried the above command in the Emacs source code and got 108,000 hits, mostly false alarms. I had better luck with this:

find . -name test -prune -o '(' -name '*.el' -o -name '*.c' ')' -exec \
  grep --color -nH -Ee \
  "[\`'‘][[:alpha:]][[:alnum:]]*-[[:alnum:]-]*[[:alnum:]][’']" \
  {} +

This yields only 39,000 hits, mostly not false alarms. Although this is the sort of thing one would want to package up rather than type by hand, the curved quotes aren't the major reason for needing packaging.
