Obsolete, broken code in zsh/config.zsh

[Klaus Hartl]

I believe the following code in zsh/config.zsh is obsolete and should be removed:

if [[ -n $SSH_CONNECTION ]]; then
  export PS1='%m:%3~$(git_info_for_prompt)%# '
else
  export PS1='%3~$(git_info_for_prompt)%# '
fi

PS1 is not used as soon as PROMPT is set (which is done elsewhere in these dotfiles), furthermore the function git_info_for_prompt seems to no longer exist.
