Comment:

 Ok, I think the core of this bug is that the parser can't read what the
 writer emits:

 {{{
 SELECT ST_AsEwkt(geometry(ST_Collect('MULTIPOINTM((1 1 1))', 'POINTM(5 5
 5)')) )::geometry;
 ERROR:  can not mix dimensionality in a geometry
 }}}

 Note that dropping the ::geometry part you get no error, so the error is
 at parse time, and the error is correct. So the bug is in ST_AsEwkt. I'm
 on it.
