如何grep git diff？

有没有办法显示通过给定模式过滤的git-diff。

就像是

git grepdiff pattern

changed file
+++ some sentence with pattern
changed file 2
--- some other pattern

不幸的是，最简单的解决方案还不够好

git diff | grep pattern 

+++ some sentence with pattern
--- some other pattern
# not an option as doesn't put the filename close to the match

我使用awk提供了一种解决方法

git diff | awk "/\+\+\+/{f = \$2}; /PATTERN/ {print f \$0} "

但是很乐意找出对此有一个命令。
