PostGIS Box2D (and && operator) gives wrong result for ST_CircularString type

Description
Box2D is supposed to support ST_Curve types, but obviously, albeit calling Box2D with an ST_CircularString causes no error, the returned box is wrong. See three cases in the SQL sample file attached (circle, half-circle, "half-infinity" glyph).
Consequently, the && operator is also buggy, which prevent spatial queries to work reliably.
Seems same bugs exist in trunk (tested by Olivier Courtin, OsLandia).
