Hi,
I am learning python to reslove issue,which make happy:)
But, i am facing an interesting question.I have no idea to deal with it.
The text i will working as follow:
```text
[PATCH] perf tools: Fix copyfile_offset update of output offset
We need to increase output offset in each iteration,
not decrease it as we currently do.
I guess we were lucky to finish in most cases in first
iteration, so the bug never showed. However it shows a
lot when working with big (~4GB) size data.

In fact, this is a patch from lkml,my goal is to design a kernel podcast
for myself to focus on what happened in kernel. I have crawled the text
with python and want to remove strings from *diff --git*, because reading
the git commit above, i have a shape in head.
I have tried split(), replace(), but i have no idea to deal with it.
I will appericate if you have any idea.
Thanks!
