From b079c50e03a812f5c8197b8f38e0a5fe6dd31321 Mon Sep 17 00:00:00 2001 From: Thomas Rast Date: Thu, 19 Feb 2009 22:26:31 +0100 Subject: format-patch: track several references Currently, format-patch can only track a single reference (the In-Reply-To:) for each mail. To ensure proper threading, we should list all known references for every mail. Change the rev_info.ref_message_id field to a string_list, so that we can append references at will, and change the output formatting routines to print all of them in the References: header. The last entry in the list is implicitly assumed to be the In-Reply-To:, which gives output consistent with RFC 2822: The "References:" field will contain the contents of the parent's "References:" field (if any) followed by the contents of the parent's "Message-ID:" field (if any). Note that this is just preparatory work; nothing uses it yet, so all "References:" fields in the output are still only one deep.
