[PATCH v4 08/11] cli: Make notmuch-show respect excludes.

[Mark Walters]

This adds the excludes to notmuch-show.c. We do not exclude when only
a single message (or part) is requested. notmuch-show will output the
exclude information when either text or json format is requested. As
this changes the output from notmuch-show it breaks many tests (in a
trivial and expected fashion).
