I looked for hunks that don't 1:1 replace "Note:" or "Notes:" by
".. note::."  Findings:

* Two hunks replace by ".. caution::" instead.  Commit message got it.
  Good.

* Four hunks replace by ".. admonition:: notes", one of them as a test.
  Commit message got it.  Good.

* Three hunks split "Notes:" into multiple ".. note::".  Good, but could
  be mentioned in commit message.

* Two hunks drop "Note:", changing it into paragraph.  The paragraph
  merges into the preceding "Example" section.  Good, but should be
  mentioned in the commit message, or turned into a separate patch.

* One hunk adjusts a test case for the removal of the "Note:" tag.
  Good, but could be mentioned in the commit message.

Perhaps tweak the paragraph above:

  This patch uses ".. note::" almost everywhere, with just two "caution"
  directives. Several instances of "Notes:" have been converted to
  merely ".. note::", or multiple ".. note::" where appropriate.
  ".. admonition:: notes" is used in a few places where we had an
  ordered list of multiple notes that would not make sense as
  standalone/separate admonitions.  Two "Note:" following "Example:"
  have been turned into ordinary paragraphs within the example.

Okay?

I dislike the indentation changes, and may revert them in my tree.
