That looks good. I've switched it to that with a comment about the
non-empty issue.

So do I and I'll add it to the example. I was just suprised that
compinit added duplicates.

ok. I'll put it in even though it ceases to be a nice simple example.
I'd like yp and yu from Functions/Example in here instead because
they are simple and easy to understand.

Has anyone got a useful and very short user-defined zle widget we could
add?

That would either need zmodloading zsh/parameter, a redirected which or
redirected stderr from unfunction. I think I'd prefer to keep it simple,
I'm even tempted to remove the while loop. If you prefer, either change
it or remove the function, I'm not really bothered but I've left it as
above for now.

I thought it was meant to be an example really as opposed to being
generic but judging from the comment at the top, maybe I'm wrong. That
isn't a line I added it was there before and I think it serves a useful
purpose in showing that you can setup your manpath there. I also think
it wouldn't be a bad thing if the examples break lots of things to
force them to be read before being used.

If you really want to remove those lines, I don't mind but following
the same principle much of zlogin and all of zshenv would also have to
go too.

Anyway, I'm going to be away for a few days so I'll commit this now
before I forget. Patch is to be applied on top of the previous. I also
added a few zmodload -a commands.

Ok, thanks, I've also updated that line before it is forgotten.
