This gets us into ugly license conflict territory.

The check-code code is GPL. So including it here is likely to cause some
(minor) confusion about the overall hglib license or of check-code. Not
a big deal. But in patch 4, you import it from MIT-licensed code and use
it - oops, now the MIT-licensed code is effectively GPL.

So I'm going to defer dealing with these three patches for now.
