 Sorry, I should have mentioned that I use (quite old) 4.3.10 (from Debian
Squeeze).

 I tried grabbing just the latest _git but it fails with

_arguments:comparguments:312: invalid argument: (-v          --header)

error so it looks like I'd have to install a new zsh version locally.

 Anyhow, thank you and Axel for your answers, at least I won't waste time
trying to understand how to do it myself.

 Thanks,
