I thought it does. I think it is the other way round. !\"CONTENT\" is supported

However content:"!PASS"; does. unit test attached to display the issue.

This isn't supported.

The test patch you supplied would fail, because you have called SigTestNegativeTestContent and not SigTestPositiveTestContent.

If you meant \"!PASS\" should also be supported, here is a patch.;
