Subject: git log -p unexpected behaviour - security risk?
Message-ID: <CAHQ6N+qdA5Lck1_ByOYPOG4ngsztz3HQSw8c_U_K8OnDapj4bQ@mail.gmail.com>

Hi,

  I noticed that code that you put in merge will not be visible by
default.  This seems like a pretty horrible security problem, no?

I made the following test tree, with just 3 commits:

https://github.com/johnflux/ExampleEvilness.git

Doing "git log -p"  shows all very innocent commits.  Completely
hidden is the change to add "EVIL CODE MUWHAHAHA".

This seems really dangerous!

The evil code only shows up with the non-default  --cc or -m  option.

Is there a way to make --cc default?

John
