This is a idea to relax/extend lm-keywords to cope with multi-line
keywords, like say Drew's icicles.el,

  ;; Keywords: internal, extensions, help, abbrev, local, minibuffer,
  ;;           keys, apropos, completion, matching, regexp, command

And comma-only separators like say zenirc-color.el,

  ;; Keywords: zenirc,extensions

And trailing-space as in say vm-summary-faces.el, which had been ok in
Emacs 21.

  ;; Keywords:    VM

	* emacs-lisp/lisp-mnt.el (lm-keywords): Allow multi-line keywords.
	(lm-keywords-list): Allow comma-only separator like "foo,bar".
	Ignore trailing spaces by omit-nulls to split-string (fixing
	regression from Emacs 21 due to the incompatible split-string
	change.)
