"HEAD should resolve as a tag" is not sensible, but "HEAD should
locally DWIM to something sensible" is still possible, no?

We could for example make the rule for unset $3 case like this,
instead of the current "missing $3 is a request to pull HEAD":

    If you have one and only one signed tag that happens to point at
    the commit sitting at HEAD, behave as if that tag was given as
    the third argument from the command line.

    Otherwise, if you are on a branch, behave as if that branch was
    given as the third argument from the command line.

    If you are not on any branch, error out.
