I hadn't thought of doing it that way and had only read the text not the patch in your message so hadn't seen it. I agree with your past comments about stomping on precmd though and think it is better not to use precmd just for one setopt which doesn't need to be run every time the prompt is printed anyway.

That works well, thanks.

I did that because it seemed an easy way to restrict it to the prompt options.

That probably is better. An alternative patch to do it that way follows. The only thing I'm not sure about is whether it is wise that promptcr is controlled by the prompt themes. I'd consider it to be down to personal preference whether it's set or not. I also can't see that it could be crucial to a particular theme so you might want to remove cr from the brace expansion.

Incidentally, I had to use prompt${^prompt_opts[@]} instead of what you suggested because after emulate -R ksh, only the first word in the array would be expanded.
