Should be.  Unfortunately dwarfed by the field motion constraints :-(

It takes me more time to understand something like

  This function constrains the returned position to the current field
  unless that would be on a different line than the original,
  unconstrained result.  If N is nil or 1, and a rear-sticky field ends
  at point, the scan stops as soon as it starts.

than to code `forward-line' within a `save-excursion'.  YMMV.
