[PATCHv3 0/5] Handling empty notes

Changes v1 -> v2:
 - Incorporate Eric's feedback
 - Factor out an initial fix, needed before adding the tests

Changes v2 -> v3:
 - Incorporate Junio's feedback
 - Move tests from t3312 to t3301
 - Refactor the display of empty notes (the part concerning
   git-log) into a separate follow-up patch (#4)
 - Add a final (optional) patch with some whitespace and other
   cleanups in t3301. Feel free to drop this if it's too much
   churn.

Have fun! :)
