And probably "v1.0", as well, in this iteration. :)
The patch content itself looks good to me, except:

What's this "column" stuff doing here? The nd/columns topic is still in "next", isn't it? Did you base this on "next" or "pu"?

Usually topics should be based on master, so they can graduate independently of each other. In this case, it might make sense to build on top of jk/maint-tag-show-fixes (d0548a3), but I don't think that is even necessary here (my fixes ended up not being too closely related, I think).

Other than that, I think the patch is fine. There are no tests, so perhaps these should be squashed in:
