The git prompt format is ${GIT_PROMPT_PREFIX}<BRANCH><TRACKING>${GIT_PROMPT_SEPARATOR}<LOCALSTATUS>${GIT_PROMPT_SUFFIX}

BRANCH is a branch name, such as "master" or "stage", a tag name, or commit
hash prefixed with ':'.

TRACKING indicates how the local branch differs from the
remote branch.  It can be empty, or one of:

    ${GIT_PROMPT_BRANCH}${ResetColor}${GIT_PROMPT_REMOTE}${GIT_PROMPT_SYMBOLS_AHEAD}N${ResetColor} - ahead of remote by N commits
    ${GIT_PROMPT_BRANCH}${ResetColor}${GIT_PROMPT_REMOTE}${GIT_PROMPT_SYMBOLS_BEHIND}M${ResetColor} - behind remote by M commits
    ${GIT_PROMPT_BRANCH}${ResetColor}${GIT_PROMPT_REMOTE}${GIT_PROMPT_SYMBOLS_AHEAD}N${GIT_PROMPT_SYMBOLS_BEHIND}M${ResetColor} - branches diverged, other by M commits, yours by N commits

LOCALSTATUS is one of the following:

    ${GIT_PROMPT_CLEAN}${ResetColor} - repository clean
    ${GIT_PROMPT_STAGED}N${ResetColor} - N staged files
    ${GIT_PROMPT_CONFLICTS}N${ResetColor} - N files with merge conflicts
    ${GIT_PROMPT_CHANGED}N${ResetColor} - N changed but *unstaged* files
    ${GIT_PROMPT_UNTRACKED}N${ResetColor} - N untracked files
    ${GIT_PROMPT_STASHED}N${ResetColor} - N stash entries

See "git_prompt_examples" for examples.
