I think we ought to use -0 here. I can't find any reference to anyone
using -Z or --null with grep via Google, nor is it in the POSIX spec,
so I think it's more important to be consistent internally than
externally here.

What was this doing?

-a needs to be --text, like grep(1) and hg diff.

If we support -e, we need to support multiple patterns (which is what
it's there for in grep(1)).

How does hg cat help? It only handles one file/version. Invert
colliding with verbose is a bit of a problem.

Agreed.

And what was this doing?

POSIX grep uses -f to indicate a file containing regexes.
