[PATCH v3 00/13] Convert notmuch show to use structure printers

[Austin Clements <amdragon@MIT.EDU>]

Relative to version 2 [0], this version fixes a duplicate typedef of
struct sprinter that was not standards compliant and failed to compile
on older gccs [1] (thanks to Tomi for discovering that and figuring
out what was going on).

The diff relative to version 2 follows.
