# After (branch name), you'll see one or more of
#   • uncommitted changes in green
#   • unstaged changes in yellow
#   • untracked files in blue(ish)
#   1 number of stashes for this branch, also in blue(ish)
#
#  To match the bullet colors with git status colors, add
#
#  [color "status"]
#    added = green
#    changed = yellow
#    untracked = blue
#
#  to your ~/.gitconfig.
