Here is my current custom, but I don't know how to customize its face. And it only shows branch name, no other status info.
(setq-default mode-line-format (quote ((:eval (if vc-mode (progn (list (propertize " ⭠" 'face '(:foreground "sky blue")) ;; TODO: propertize this. set face height to 75 `(vc-mode vc-mode) )))) )))
I hope someone can give out a better solution.
Or at least tell me how to custom my upper status
(vc-mode vc-mode) face.
