The external spatial functions got them added, so all match up to the
standards base. The internal functions, used for casts got them
stripped to match PostgreSQL convention: newtype(oldtype) is the
PostgreSQL standard casting function signature. There are some other
even more internal functions (type_in(), type_out()) that you don't
see or use that also had their st_ prefixes stripped. They really
should never have had them added in the first place.
