Yes, that page describes all of the grep enhancements, for different Emacs
versions - the specifics are mentioned there.

OK. I just added similar commands to compile+20.el, for use with Emacs
versions prior to 22: http://www.emacswiki.org/cgi-bin/wiki/compile%2b20.el.
However, since there is no grep-specific keymap prior to Emacs 22, I have
not bound the new commands.
