[PATCH v2 0/8] Rewrite JSON show format

[Austin Clements]

v2 fixes some trivial whitespace issues in devel/schemata [1] and
beefs up one of the explanations in devel/schemata.  None of the other
patches have changed, so I'm marking this ready.

As a teaser, I've got mbox and raw converted to the new style, too, so
as soon as this goes in I'll send those patches (they aren't actually
dependent, but do share some diff context with this one).
