D5832: config: extract diff-related coreconfigitem()s to a helper method

REVISION SUMMARY
  We already have 'annotate' and 'diff' that use the same set of options, and I
  want to add more in a followup commit, so I'm attempting to reduce maintenance
  burden and duplication by making it possible to register all of them at once.
