It looks like fmt-merge-msg looks in FETCH_HEAD to see if each line is
marked as "branch" or "tag". So I get "Merge tag ..." with:
git pull . tag v1.0
but I get "Merge commit ..." with:
git merge v1.0
When "git merge" is run, it actually creates a fake FETCH_HEAD in memory
and feeds it to fmt-merge-msg. But that process doesn't seem to bother
looking at tags. I think we just need this:
---
diff --git a/builtin/merge.c b/builtin/merge.c
index dffd5ec..6a44b6d 100644
--- a/builtin/merge.c
+++ b/builtin/merge.c

where the result of merge_name is just fed to fmt-merge-msg eventually.
