Subject: [PATCH v2 3/3] git-prompt.sh: enable color prompt in non-pcmode
Message-ID: <1371521986-10179-1-git-send-email-erdavila@gmail.com>
In-Reply-To: <7vhagxicu9.fsf@alter.siamese.dyndns.org>

The use of colors in a prompt is only possible in
pcmode (using the variable PROMPT_COMMAND).

Enable color prompt in non-pcmode (using the variable
PS1) for both Bash and ZSH.
