The help tests would not pass because in cases where the verb synopsis
is very long, we'd format the table badly if the terminal is fairly
narrow. I experimented with a few solutions, but overall, it's hard to
achieve very good layout with the automatic formatting. I think the
approach in this commit works the best: we end up with an two- or
three-line verb synopis, which is similar to what we did manually
before.

I think that almost nobody actually uses an 80 column terminal, and if
they do, they probably don't spend too much time looking at our --help
output there. So the goal here is to do something reasonable and robust
and get the tests to pass.
We can use strjoina here because the strings are fully under our
control.
