Subject: merge: record tag objects without peeling in MERGE_HEAD
X-Git-Tag: v1.7.9-rc0~1^2~12
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=274a5c06d525da8c9720ae60454fba6779523c52;p=git.git

merge: record tag objects without peeling in MERGE_HEAD

Otherwise, "git commit" wouldn't have a way to tell that we were in the
middle of merging an annotated or signed tag, not a plain commit, after
"git merge" stops to ask the user to resolve conflicts.
