Subject: notmuch_database_add_message: Do not return a message on failure.
X-Git-Tag: 0.1~677
X-Git-Url: https://git.notmuchmail.org/git?p=notmuch;a=commitdiff_plain;h=203a717d64864411eb6802c06a5a0ad1cf98e077;ds=sidebyside

notmuch_database_add_message: Do not return a message on failure.

The recent, disastrous failure of "notmuch new" would have been
avoided with this change. The new_command function was basically
assuming that it would only get a message object on success so
wasn't destroying the message in the other cases.
