[PATCH v3 0/3] Colored prompt for ZSH

One minor change, in accordance with Junio's review. In part 1, I use:

local z="${GIT_PS1_STATESEPARATOR-" "}"

Instead of the convoluted:

local z=" "
if [ -n "${GIT_PS1_STATESEPARATOR+set}" ]; then
	z="${GIT_PS1_STATESEPARATOR}"
fi

Everything else is the same. I've rebased it on top of the latest `master`.

Ramkumar Ramachandra (3):
  prompt: introduce GIT_PS1_STATESEPARATOR
  prompt: factor out gitstring coloring logic
  prompt: colorize ZSH prompt
