Oops, yes. That's obviously wrong. Thanks for noticing.
That should be: PS1='%F{5}[%F{2}%n%F{5}] %F{3}%3~ ${vcs_info_msg_0_}%f%# '

Absolutely. I thought I had mentioned it. Seems like I forgot.

Patch for both issues included below.

Well, a lot of people (me included) build their prompt in precmd().
That way you can always get the fresh value out of $vcs_info_msg_0_
without having to use prompt_subst. Here is how I am building my
prompt, if you're wondering what I'm talking about:

 Obviously, the last two lines are there for demonstration: You need to
 call var(vcs_info) from your var(precmd) function. Once that is done you need
 a tt(single quoted) var('${vcs_info_msg_0_}') in your prompt.
 
+To be able to use var('${vcs_info_msg_0_}') directly in your prompt like
+this, you will need to have the tt(PROMPT_SUBST) option enabled.

 Now call the tt(vcs_info_printsys) utility from the command line:
 
 example(% vcs_info_printsys
