Sorry, but I happen to think the proposed implementation is somewhat
inelegant:

  . what's with the "(interactive (list nil))" part?
  . why not just make ispell-comments-and-strings accept a prefix
    argument to modify its behavior?
  . alternatively, why not make ispell-comments-and-strings be
    sensitive to the active region?
  . as yet another alternative, make the new ispell-comment-or-string
    narrow to the comment/string at point and then call
    ispell-comments-and-strings with no code changes whatsoever; then
    make the new command be sensitive to active region, and fall back
    on the string/comment at point if no active region
