Patch Set 4: I would prefer that you didn't submit this; No score

I found the following problems :

style nits:
- some typos in the commit message
- an extra blank line after header of commit message

I think the basic creation of patch and git patch should be implemented in jgit since there will be other usages (e.g. command line).

- create git patch:
  - date: header seems to be wrong, compare against result of c-git format-patch output
  - would be nice to also get diffstat like c-git format-patch does by default
  - if comparing output to c-git "format-patch --no-stat" it looks like you generate an extra "---" line
