I was under the impression that the packages you describe on the

  http://www.emacswiki.org/cgi-bin/emacs/GrepPlus

page implement the GrepPlus functionality for emacs21 and earlier, and
also for emacs22.

You made this modification in grep+.el which is for emacs 22. I thought
you would add the same functionality to compile-20.el or compile+20.el,
so that these enhancements can be used on emacs21 too.
