Right, I think you'd need a pretty crazy bug in order to slip through
all tests here.

Well, the general bug/behavior was always there, but I regressed a
particular use-case. In 2.14, you could do `git tag` with column.ui=auto
and it would do the columns-thing. But with ff1e72483, the behavior
changed. To add insult to injury, it might be non-obvious that the pager
is running, since with just a few tags, the pager simply exits silently.
So debugging this could probably be quite frustrating.
