[PATCH 0/3] suppress trailing whitespace on empty "notes" lines

This patch series fixes a problem in which `git format-patch --notes`
and `git log` unconditionally indent _all_ "notes" lines, including
those which are empty, which ends up leaving (unwanted) trailing
whitespace on the previously empty lines. The first couple patches
adjust some existing notes-related tests -- which undesirably hard-code
those indented blank notes lines -- to be less brittle since they would
otherwise break by the change made in the final patch which fixes the
actual problem.

Eric Sunshine (3):
  t3301: tolerate minor notes-related presentation changes
  t3303/t9301: make `notes` tests less brittle
  notes: don't indent empty lines
