Yes, sorry , my snippet was too short:


git_info() {
   ref=$(git symbolic-ref -q HEAD 2>/dev/null)
   ref=${ref#refs/heads}
   echo ${ref:+"${GREEN}[$ref]${WHITE}"}

EXITCODE='%(?..(%?%))'
precmd () {
   PS1="%m%F{red}${EXITCODE}%f%# "
   RPROMPT="$(git_info)%30<..<%/"

   case $TERM in
     (xterm*|rxvt|mrxvt)
     print -Pn "\e]0;%n@%m: $1\a"
     ;;
   esac
}

And to follow your script hint ( with the erronous precmd version above ) :

$ date%
$(127)
$ script zsh.out
Script started, file is zsh.out
$ date%
zsh: command not found: date%
$ <CTRL-D>
Script done, file is zsh.out
$ cat zsh.out
Script started on Sun 24 Jan 2010 10:42:39 AM CET
$ date%
zsh: command not found: date%
$(127)

Script done on Sun 24 Jan 2010 10:43:06 AM CET
$ date%
$(127)

So apparently , the script program swallows the "dangling" control 
character and the shell behaves as expected ...
