Subject: cli: generalize use of GMIME_SIGNATURE_{ERROR,STATUS} to gmime-3
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=c7b9bdb81e49321170dc6f0a522301f28e791521;p=notmuch.git

cli: generalize use of GMIME_SIGNATURE_{ERROR,STATUS} to gmime-3

The ERROR enum is merged into to the STATUS enum, and the set of flags
is different.
