It is not that I do not believe that $u needs to duplicate %% in
ZSH, but I hate it when I do not understand the explanation.  Could
you help me clarify what you meant by "codes" and "like they are \ in bas"?

Are you referring to things like \u (user) \h (host) as "code" and
"bas" was a simple typo of "bash"?  In other words, is my reading
below:

	... because '%' is used as an introducer of prompt
	customization in zsh (just like bash prompt uses '\' to
	introduce \u, \h, etc.), we need to give '%%' to get a
	literal per-cent character.

match what you meant to say?
