// In order to use multi-line comments, you must use the "comfort fade" preview.

//   [Start]Side, and [Start]Line.
// These new fields must be used for ALL comments (including single-line),
// with the following restrictions (empirically observed, so subject to change).
//
// For single-line "comfort fade" comments, you must use:
//
//    Path:  &path,  // as before
//    Body:  &body,  // as before
//    Side:  &"RIGHT" (or "LEFT")
//    Line:  &123,  // NOT THE SAME AS POSITION, this is an actual line number.
//
// If StartSide or StartLine is used with single-line comments, a 422 is returned.
//
// For multi-line "comfort fade" comments, you must use:
//
//    Path:      &path,  // as before
