If instead of being inside set-fret, this check took place in the form of a
(string-qualifies string (note-pitch note)) check at line 455, we could
issue the warning and then try to find a valid fretboard/tablature that
would handle the pitch, assuming the string number was incorrect.  That way,
we'd still have the note in play, and the string would be available for
other notes.

I think that's a more robust way to handle it than setting the negative fret
