Pls see attached files: I have a Patcher java which I use to apply a sequence 
of patches to the source code and I have a PatcherTest that fails with the 
following stack trace:

Please checkout attached tarball of the project: I have added a tst for the 
issue and fixed the code (see DiffUtils.generateUnifiedDiff, lines 143-145). 
Prior to the fix empty lines were ignored, however they were produced by 
unified diff as a part of context if the original source contained empty lines. 
Hope this helps.

I would like to further contribute to the project, can I get access?
