Ah, if the actual behaviour directly contradicts the documentation, then
either the behaviour is buggy, or the documentation is in error. In this
case I agree with Bram that, in the light of the "principle of least
surprise", it's probably better (but maybe not as easy to fix) to regard
the documentation as right and fix the C code than the opposite.
Best regards,
Tony.
