[JGIT PATCH 7/6] BROKEN: Add a zero line context test for diff.DiffFormatter

["Shawn O. Pearce" <spearce@spearce.org>]

Signed-off-by: Shawn O. Pearce <spearce@spearce.org>
---

 This test currently fails because it shows the difference between
 the way CGit and JGit number a zero context line patch.

 Either we hack JGit to match CGit here, or we modify the test
 vector, or CGit agrees there's a bug and fixes their code, and we
 modify the test vector.
