[PATCH v2 11/14] cli/reply: return internet address list from get header funcs

Jani Nikula jani at nikula.org
Sat Aug 13 04:37:35 PDT 2016


Pass in GMimeMessage to simplify To/Cc/Bcc headers. We'll eventually
remove the notmuch message passing altogether, but keep both for now
to not make too big changes at once.

Getting the headers from GMimeMessage using GMime functions fixes the
error on duplicate Cc headers reported by Daniel Kahn Gillmor
<dkg at fifthhorseman.net> in id:87d1ngv95p.fsf at alice.fifthhorseman.net.

Get rid of an intermediate function.

The small annoyance is the ownership differences in the address lists.
