You did not realize, but the above relies on the old-style backquote
syntax, which has been further phased out (it's been obsolete for a very
long time now).  So now (control ,) fails in the same way as (control
').  Use [(control ?,)] or [(control \,)] instead (which will work for
older emacsen as well).
