Further, `set_point_both' contains the following comments:

	  /* If the preceding character is both intangible and invisible,
	     and the invisible property is `rear-sticky', perturb it so
	     that the search starts one character earlier -- this ensures
	     that point can never move to the end of an invisible/
	     intangible/rear-sticky region.  */
	  charpos = adjust_for_invis_intang (charpos, -1, -1, 1);
	  <...>
	  /* If the following character is both intangible and invisible,
	     and the invisible property is `front-sticky', perturb it so
	     that the search starts one character later -- this ensures
	     that point can never move to the beginning of an
	     invisible/intangible/front-sticky region.  */
	  charpos = adjust_for_invis_intang (charpos, 0, 1, 1);

However, 'intanglible text property is, in fact, not necessary to
trigger the adjustment.

I meant info node.
