Another possibility is to split inhibit-point-motion-hooks into two
separate variables that suppress point-entered/point-left and use of
the intangible property respectively.  In that case, both
Fline_beginning_position and the relevant part of line-move-1 would
inhibit use of point-entered/point-left while allowing use of the
tangible property.
