$ git diff --help

EDIT:

After some tests I've got something like

Then I've got output like:

index 62a2de0..b76891f 100644
--- a/test.php
+++ b/test.php

diff --git a/test1.php b/test1.php
index 62a2de0..6102fed 100644
--- a/test1.php
+++ b/test1.php

Maybe it will help you. I found it here http://www.rhinocerus.net/forum/lang-lisp/659593-git-word-diff-regex-lisp-source.html and there is more information on this thread

EDIT2:

git diff -G'\[[A-Za-z_]*\]' --pickaxe-regex
