Actually, I can think of one reasonable behavior: if goal-column is
set to a non-nil value, ignore the value of line-move-visual and
always move by logical lines.  This will do the same as it does today
when lines are not wrapped, and do the only reasonable thing
otherwise.

Technically, this means that line-mode should call line-move-1 if
goal-column is set, even if line-move-visual is non-nil.

Thoughts?
