[PATCH] Automatically exclude tags in notmuch-show

[Austin Clements]

LGTM, but should definitely come with a test.

Also, this won't commute with Pieter's patch
(id:"1327000744-25463-2-git-send-email-pieter at praet.org"), so one or
the other will have to get updated.

Hah.  The original patch series updated 'count' to use the new
argument parsing solely so I could steal 'i' for the tag exclude code.
