Subject: Remove the talloc_owner argument from create_for_message_id.
X-Git-Tag: 0.1~469
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=24a25ffba98c1c34d92cefb9e23dd44e3be76126;p=notmuch.git

Remove the talloc_owner argument from create_for_message_id.

This function has only one caller, and that one caller was passing the
same value for both talloc_owner and the notmuch database. Dropping
the redundant argument simplifies the documentation of this function
considerably.
