Subject: [PATCH] This commits affects how these variables are populated by
 git_prompt_status():

* STATUS
* ZSH_THEME_GIT_PROMPT_UNTRACKED
* ZSH_THEME_GIT_PROMPT_ADDED
* ZSH_THEME_GIT_PROMPT_MODIFIED

New values are calculated in a different way to actually represent their name, using
only git commands and flags/switches.
