From 5231c633f2e54723d53a8cd928d9bc98b39dc35f Mon Sep 17 00:00:00 2001 From: Junio C Hamano Date: Mon, 7 Nov 2011 16:21:32 -0800 Subject: commit: copy merged signed tags to headers of merge commit Now MERGE_HEAD records the tag objects without peeling, we could record the result of manual conflict resolution via "git commit" without losing the tag information. Introduce a new "mergetag" multi-line header field to the commit object, and use it to store the entire contents of each signed tag merged. A commit header that has a multi-line payload begins with the header tag (e.g. "mergetag" in this case), SP, the first line of payload, LF, and all the remaining lines have a SP inserted at the beginning. In hindsight, it would have been better to make "merge --continue" as the way to continue from such an interrupted merge, not "commit", but this is a backward compatibility baggage we would need to carry around for now.
