Thanks.

Byte-compiling this I get two warnings:

    ELC      emacs-lisp/ert-font-lock.elc

  In ert-font-lock--parse-macro-args:
  emacs-lisp/ert-font-lock.el:82:19: Warning: Unused lexical variable `keys'

  In ert-font-lock--comment-start-p:
  emacs-lisp/ert-font-lock.el:191:10: Warning: `derived-mode-p' called with 3 arguments, but accepts only 1

Could you please fix these and resubmit the patch?
