ansi-color.el is good for displaying highlighted substrings,
but it _deletes_ escape sequences after highlighting the substrings.
So, as Daniel pointed out, substrings can't be rehighlighted later
after saving and reloading the *grep* buffer.  Moreover, ansi-color.el
conflicts with font-lock which is used to calculate column positions
of matches based on relative locations of escape sequences in grep output.
