[PATCH v3 00/10] range-diff: learn `--notes`

[Denton Liu <liu.denton@gmail.com>]

This patchset teaches range-diff and format-patch to pass `--notes`
options down to the `git log` machinery. This should make the behaviour
more configurable for users who either don't want notes to be displayed
or want multiple notes refs to be displayed.

Changes since v2:

* Changed --notes=<treeish> to --notes=<ref>

* Added "t3206: disable parameter substitution in heredoc"

* Updated the commit message of "range-diff: pass through --notes to `git log`"

Changes since v1:

* Complete overhaul of approach

Denton Liu (10):
  argv-array: add space after `while`
  rev-list-options.txt: remove reference to --show-notes
  pretty-options.txt: --notes accepts a ref instead of treeish
  t3206: remove spaces after redirect operators
  t3206: disable parameter substitution in heredoc
  t3206: s/expected/expect/
  t3206: range-diff compares logs with commit notes
  range-diff: output `## Notes ##` header
  range-diff: pass through --notes to `git log`
  format-patch: pass notes configuration to range-diff

         range-diff and format-patch when notes were present. Cover this

         When a commit being range-diff'd has a note attached to it, the note
         will be compared as well. However, if a user has multiple notes refs or
         if they want to suppress notes from being printed, there is currently no
         way to do this.
