fix errno value for getcwd when size argument is zero
based on patch by Michael Forney. at the same time, I've changed the if branch to be more clear, avoiding the comma operator. the underlying issue is that Linux always returns ERANGE when size is too short, even when it's zero, rather than returning EINVAL for the special case of zero as required by POSIX.
