[PATCH 2/4] reply: Add a JSON reply format.
Adam Wolfe Gordon

Sat Jan 7 23:52:40 PST 2012
From: Adam Wolfe Gordon <awg at xvx.ca>
This new JSON format for replies includes headers generated for a reply
message as well as the headers and all text parts of the original message.
Using this data, a client can intelligently create a reply. For example,
the emacs client will be able to create replies with quoted HTML parts by
parsing the HTML parts using w3m.
