[PATCH] prompt: fix tracked files for zsh

[Felipe Contreras]

When this option is enabled, the prompt gets totally screwed in zsh
because all the codes start with % in zsh (like they are \ in bas). So
we need to escape the % character.

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?

Do you need/want a colon there?  Even if it is empty, as long as it
is defined we would want this, no?

The original wouldn't.

I thought you were trying to improve the original ;)

OK, so I _think_ everybody is in agreement that the patch should
look like this.  OK?

Subject: [PATCH] prompt: fix untracked files for zsh

With "bash.showUntrackedFiles" option, presense of untracked files
is signalled by adding a per-cent sign '%' to the prompt.  But
because '%' is used as an escape character to introduce prompt
customization in zsh (just like bash prompt uses '\' to escape \u,
\h, etc.), we need to say '%%' to get a literal per-cent.

Not exactly correct, it can also be GIT_PS1_SHOWUNTRACKEDFILES.

Otherwise it's fine.
