[PATCH v7 00/13] tr/display-notes

Here's a hopefully last replacement for the series. I implemented Johan's requests for changes and collected his acks; the only behavioral change is that format_display_notes() no longer calls init_display_notes() implicitly.

Thomas Rast (13):
  test-lib: unset GIT_NOTES_REF to stop it from influencing tests
  Support showing notes from more than one notes tree
  Documentation: document post-rewrite hook
  commit --amend: invoke post-rewrite hook
  rebase: invoke post-rewrite hook
  rebase -i: invoke post-rewrite hook
  notes: implement 'git notes copy --stdin'
  notes: implement helpers needed for note copying during rewrite
  rebase: support automatic notes copying
  commit --amend: copy notes to the new commit
  notes: add shorthand --ref to override GIT_NOTES_REF
  notes: track whether notes_trees were changed at all
  git-notes(1): add a section about the meaning of history
