want to start over, you can recover with `git merge --abort`.
MERGING TAG
-----------
When merging an annotated (and possibly signed) tag, Git always
creates a merge commit even if a fast-forward merge is possible, and
the commit message template is prepared with the tag message.
Additionally, if the tag is signed, the signature check is reported
as a comment in the message template. See also linkgit:git-tag[1].
When you want to just integrate with the work leading to the commit
that happens to be tagged, e.g. synchronizing with an upstream
release point, you may not want to make an unnecessary merge commit.
In such a case, you can "unwrap" the tag yourself before feeding it
to `git merge`, or pass `--ff-only` when you do not have any work on
your own. e.g.
---
git fetch origin
git merge v1.2.3^0
git merge --ff-only v1.2.3
