Subject: [PATCH] color: fix have_fg not re assign to true
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

In method _parse the value of this variable 'have_fg ' is always
False, Maybe reassign it to True is lost.
I guess the author’s original intention was:
if set some value in gitconfig file(for ex: text = black red ul),
the first is bg color, the second is fg color, and the last one is attr.
