Comment (by pramsey):

 Confirmed, this polygon
 {{{
 MULTIPOLYGON(
  ((0 0,100 0,100 100,0 100,0 0),(10 10,90 10,90 90,10 90,10 10)),
  ((20 20,20 80,80 80,80 20,20 20),(30 30,30 70,70 70,70 30,30 30))
 )
 }}}
 when exported to shape and then reimported, turns into this one
 {{{
 MULTIPOLYGON(
  ((0 0,0 100,100 100,100 0,0 0),(10 10,90 10,90 90,10 90,10 10),(30 30,70
 30,70 70,30 70,30 30)),
  ((20 20,20 80,80 80,80 20,20 20))
 )
 }}}
