Refactoring _bsd_pkg

Hi,

Is anyone using _bsd_pkg with OpenBSD 3.x?

The platform for which _bsd_pkg is relevant to me is OpenBSD.  Until
today, I hadn't realised that _bsd_pkg even existed.  Having just tried
it, I think the reason I didn't notice is that it behave{s,d} incorrectly
and therefore I didn't realised that something intelligent was at work.
Also, I notice that the OpenBSD ports tree contains a patch that I can't
see in zsh CVS HEAD. I have attached the completion function that I have
been using for pkg_delete and pkg_info. Mine is concise, partly because
it does not support pkg_add, pkg_create, or other BSDs. However, there
are some salient differences. Having downloaded the _bsd_pkg HEAD, it
appears that there are some errors in it from the OpenBSD perspective
(as in previous versions). I don't know whether this is because other
BSDs are different or because no one has noticed.

Is anyone aware of these sorts of things or is it only my perception?
