Re: [PATCH] diffcore-pickaxe: make error messages more consistent

"-G" is a different variant of pickaxe.

Hm, I think it is the correct approach because readers of diffcore are
probably going to look at the source: it's not exactly an end-user
manpage.  I've not explained it as G king versus S kind in the
diff-options documentation.

Or are you just talking about the error message?  That's simple:
--pickaxe-regex is what triggers this off, and we've made it clear
that it applies to both commands (-G implicitly; see doc).
