this looks like a fine first step to me, and i hope it will be merged.
thanks for working on it, Pádraig!

I'm not convinced yet that adding --zero for the --check functionality
is a guaranteed incompatibility.  Clearly the same flags would need to
be used on both sides, but i don't see why having it available in
--check would be a problem.
