Merge branch 'dl/format-patch-notes-config-fixup'

"git format-patch" can take a set of configured format.notes values
to specify which notes refs to use in the log message part of the
output.  The behaviour of this was not consistent with multiple
--notes command line options, which has been corrected.

* dl/format-patch-notes-config-fixup:
  notes.h: fix typos in comment
  notes: break set_display_notes() into smaller functions
  config/format.txt: clarify behavior of multiple format.notes
  format-patch: move git_config() before repo_init_revisions()
  format-patch: use --notes behavior for format.notes
  notes: extract logic into set_display_notes()
  notes: create init_display_notes() helper
  notes: rename to load_display_notes()
