The tests should not depend on the OS-Version.
Please handle both possible results in the ok()

    /* Win9x+ME: 32766; WinNT: 2147483646UL */
    ok( (r == 32766) || (r == 2147483646UL),
        "got limit %u (expected 32766 or 2147483646)\n", r);

Your looks like a copy&paste error ("default text limit" is wrong here).

Change the multiline-test the same way.

To allow an easy review, you can split your patch:
one patch for the implementation and a second patch for the test.


Thanks for helping wine
