Subject: cli: search: Convert --output to keyword-flag argument
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=db307459fbc32c39f61fc894d8e77051d59dbf9b;p=notmuch.git

cli: search: Convert --output to keyword-flag argument

This converts "notmuch search" to use the recently introduced
keyword-flag argument parser. At this point, it only makes the code
slightly less readable but following commits that add new --output
keywords will profit from this.
