MFC discussed with: jilles, -developers
MFC r266971:
- Return NULL and set errno to EINVAL if size is 0 (as required by POSIX).
Update the manpage to reflect this change.
- Always set the current position to the first null-byte when opening in append
mode. This makes the implementation compatible with glibc's. Update the test
suite.
