Subject: completion: add new zsh completion

It seems there's always issues with zsh's bash completion emulation.
I've tried to fix as many as I could[1], and most of the fixes are already
in the latest version of zsh, but still, there are issues.

There is no point going through all that pain; the emulation is easy to
achieve, and this patch works better than zsh's bash completion
emulation.
