Subject: [PATCH 2/2] show color hints based on state of the git tree
Date: Wed, 10 Oct 2012 21:32:24 +0200	[thread overview]
Message-ID: <20121010193224.GA6769@simaj.xs4all.nl> (raw)
In-Reply-To: <7v7gr0k6jv.fsf@alter.siamese.dyndns.org>

By setting GIT_PS1_SHOW_COLORHINTS when using __git_ps1
as PROMPT_COMMAND, you will get color hints in addition to
a different character (*+% etc.) to indicate the state of
the tree.
