Subject: Split thread_id value on commas before inserting into hash.
X-Git-Tag: 0.1~865
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=870b3987265f74ed8b45ba0e7d7edfcca1923b5a;p=notmuch.git

Split thread_id value on commas before inserting into hash.

One thread_id value may have multiple thread IDs in it so we need
to separate them out before inserting into our hash.
