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.
