[PATCH] status: add an empty line when there is no hint

[John Lin <johnlinp@gmail.com>]

When typing "git status", there is an empty line between
the "Changes not staged for commit:" block and the list
of changed files. However, when typing "git commit" with
no files added, there are no empty lines between them.

This patch adds empty lines in the above case and some
similar cases.
