Patches in reverse format

The patches for every single bug seems to be in a reverse format. The modification made by the fix file is denoted as -, and changes from the buggy file to the fix file is denoted as +.

Hi @danielding110

This is by design. The patches introduce the bug into the "correct" version. You can think of this as a similar concept to mutation testing.
