mysqlc: next() should move cursor from Last
XResultSet::next() should move cursor when called while cursor is on the
last position. It is not documented, but older versions of the mysqlc
extension are implemented that way. The cursor goes to the so called
afterlast position.
Even so, the next() call on the last position should return false.
