REVISION SUMMARY
  We may want to define a way of formatting a context using a
  command-specific override (from
  `command-templates.oneline-summary.<command>`), but that will have to
  be a template function instead. I don't plan to do that, but I'm
  mentioning it now in case reviewers would prefer that we usea no-arg
  function (i.e. `{onelinesummary()}`) already today to prepare for
  that.
