#3090: Mutt removes In-Reply-To header field Comment (by agriffis):
...and as I said in my last sentence, this should really be merged with mutt_extract_message_id() so there's only one way that message-ids are recognized. Here's the patch. Bonus: no longer use strtok() so the input string isn't modified. This replaces all my previous patches in this bug. I've tested it for a while and it seems to fix the various problems cited. -- Ticket URL: <http://dev.mutt.org/trac/ticket/3090#comment:16>
