repo status过滤项目

repo status命令过滤没有任何改动的仓库

repo status命令正常的输出包含了所有仓库的状态信息，如果仓库数量很多的情况下，会打印大量无用信息。比如安卓源码项目AOSP，repo工具可能需要管理上百个git仓库，此时直接输入repo status命令，得到的结果几乎全部是空状态信息，如下 ：

打印仓库状态的函数是PrintWorkTreeStatus，代码路径是.repo/repo/project.py

相关代码修改后如下：

  def PrintWorkTreeStatus(self, output_redir=None, quiet=False):
    """Prints the status of the repository to stdout.
    Args:
      output_redir: If specified, redirect the output to this object.

              the modified files, branch name, etc.

修改说明：

1.通过三引号注释原有的输出内容

2.对上述输出内容进行判断
