Subject: Fix notmuch_message_maildir_flags_to_tags to iterate over filenames
X-Git-Tag: 0.5~35
X-Git-Url: https://git.notmuchmail.org/git?p=notmuch;a=commitdiff_plain;h=4b6063397ffcc13f38757e7052e3dc6649d9703c

Fix notmuch_message_maildir_flags_to_tags to iterate over filenames

As documented, this function now iterates over all filenames for the
message, computing a logical OR of the flags set on the filenames,
then uses the final result to set tags on the message.

This change fixes 3 of the 10 maildir-sync tests that have been
failing since being added.
