This test ensures a merge commit is always created
when merging an annotated (signed) tag without --ff-only option.

Here's a proposition for a test tath check the creation of a merge commit
when merging a tag.

It's not in final shape: the line 

    EDITOR=false test_must_fail git merge signed

Because test_must_fail is a shell function, single-shot environment
assignment like this should not be used.
