Thanks Asumu for merging and fixing my docs bug.
Since this was my first time contributing, I figured I'd write up what
the steps were for future first-time Racket hackers before I forget:

I'm not sure how to find the right incantation to pull this down, but
this commit looks good to push to our repo.

I think I've successfully sent a thingie to you:
https://github.com/plt/racket/pull/171
Let me know if I Did It Wrong. This is the first time I've clicked
the "Pull Request" button on Github.

Gotcha. match-pred can be a separate thing.
check-match can also let you use the identifiers bound in the match with an
optional third argument, which relies on more than match-pred anyway.
That's what I'm doing.

I think it is better to have a check-match since that way people are
more likely to find it.

I like this quite a bit. It wouldn't be crazy to add it as
match-pred(icate) right next to match-lambda, match-let, and friends (
http://docs.racket-lang.org/reference/match.html?q=match&q=match-pred#(form._((lib._racket/match..rkt)._match-lam
rackunit has check-pred, of course.

That might be nice, but a form for including a match pattern seems
like something that would be really great to have.

Predicates in general would be really awesome. I think the testing
infrastructure for Sperber's book (DMDA) has something like this.
Making it lightweight is what matters most, whether through a new
match form or a more general predicate form.

I think you should just stick "(except @racket[check-],
since its first/second argument is a match pattern)" or something like
that into the docs in your pull request.
Also test cases: I think there is a test suite for rackunit somewhere;
let me know if you have trouble with it and I can add tests

Indeed; Jonah was writing w.r.t plai, which uses test. Should use
check- in rackunit.

We use test in PLAI, and I suggested it in that context (eg,
unification, where you don't care about the gensym'ed names of logic
variables), which is probably why it got called that.

I written things like this before, so something built-in would be useful
to me too.

A small suggestion:
I used roughly this macro (credit Jonah Kagan) recently to help me write
some tests for parsing code that agnostic to which source position is
generated in the parse:
(define-syntax test/match
(syntax-rules ()
[(test/match actual expected pred)
