[JGIT PATCH 0/4] Branch deletion testing and bug fixes

Added a few tests for the RefUpdate delete method, which in turn
exposed two minor bugs. Previously you couldn't delete a ref
pointing to the current branch. Fixing that would also then allow
the current branch to be deleted too.

*** BLURB HERE ***

Charles O'Farrell (4):
  Ensured that RefUpdate cannot delete current branch
  Fixed bug where RefUpdate didn't delete identical HEAD branch
  Added test for RefUpdate branch deletion
  Added extra javadoc for delete to significant RefUpdate results
