Yes, I think you're right. Thanks for catching my error, however
belatedly. ;)

This looks good to me. Arguably these should be documented in the
definition of "struct display_notes_opt", which would have avoided the
problem (3a03cf6b1d would not have forgotten to update the name since it
would be right there already). But it may not be worth the trouble to
move them now.
