Hmm, that's definitely a good point.

If we simply omit it the output is no longer printing all the keymaps, as
it used to.  Of course, bindkey -l does that, and you can argue bindkey -lL
needs to be useful, which is after all the aim of the previous change.
Given the new behaviour is incompatible with the old, and the old was a
lie, maybe that is the right thing to do.
