[PATCH] log: decorate HEAD -> branch with the same color for branch and HEAD

["Nguyễn Thái Ngọc Duy" <pclouds@gmail.com>]

Commit 76c61fb (log: decorate HEAD with branch name under
--decorate=full, too - 2015-05-13) adds "HEAD -> branch" decoration to
show current branch vs detached HEAD. The sign of whether HEAD is
detached or not is "->" (vs ", "). It's too subtle for my poor
eyes. If color is used, we can make the branch name's color the same
as HEAD to visually emphasize that it's the current branch.
