I like this patch but for a different reason. It closes the capability
gap in zsh prompts with and without prompt_percent.

When one disables prompt_percent, they can do all the same things as
before _except_ mark some sequences as zero-width. The loss of this
capability in turn means that one cannot use colors (and many other
things) in prompt without prompt_percent.

With this patch we'll have a nice guarantee that the following two
pieces of code are equivalent:


    emulate -R zsh


    emulate -R zsh -o no_prompt_percent

(Assuming no other prompt parameters are set.)

No real-world use cases come to mind but it just looks simple and
elegant from the user's point of view.
