git doc is not an official git command so I'm not sure whether what
you're doing falls within the scope of what that contributed completion
supports but if it does then forcing ksh emulation on your function is
arguably a bug in that git completion.

I'd be very interested if you could elucidate on why you choose to use
that completion instead of the git completion that comes with zsh. It
is perhaps faster due to reduced functionality but in wrapping the bash
completion it has a much more limited interface that prevents it taking
advantage of many of zsh's more powerful features. Zsh's completion does
support handling additional commands in the same manner with, e.g. a
_git-doc function. There can be benefits to upstream projects carrying
completion functions but I usually avoid anything that wraps a bash
function.

That's relying on internal implementation details of the completion
system so you can't really rely on it.
