Sorry for not mentioning this earlier, but I do not think
multi-threaded grep has to be something we own and others cannot
implement. A richer pathspec globbing [*1*] and logical operation
on match results may be better examples of "additional benefits" if
we really wanted to mention why people might want to use
"--no-index" in a directory that is outside Git.

*1* When you want to look for something in files whose name begins
with "g" but does not have "rc" in it, you'd do
$ git grep --no-index -c . ':(exclude)*rc*' 'g*'

OK.

I actually do not think adding ", to speed up searches" is an
improvement. But referring to NOTES ON THREADS is a good idea, and
by reading that NOTES ON THREADS section, readers can tell why it
sometimes does not speed things up or even slow them down.
Other than that, looking great.
Thanks.
