FYI - I've added a command, bound to `M-;', that toggles this automatic
removal of commented lines.

The toggle command just adds and removes `remove-grep-comments' to and from
`compilation-filter-hook'. It also runs grep again to refresh the output to
have or not have (single-line) comments, according to the toggle.

(Note: This is for Emacs 22 only.)
