ST_Transform is broken for all MULTI geometries

[robe]

SELECT ST_Transform(ST_GeomFromText('MULTIPOINT(-10 40,-10 55,-10 70,5 40,5 55,5 70,20 40,20 55,20 70,
35 40,35 55,35 70,50 40,50 55,50 70)',4326), 3395);

Gives error — ERROR: lwgeom_transform: Cannot handle type 'MultiPoint'

Types that appear to be affected that used to work in 1.5:
