I added some code which should create new warnings.

Then I use the--new option, and hope to see only warnings which I introduced just now.

But there are no warnings at all.

I tried--new-from-rev=HEAD~1, too.

I have not commited my changes yet.

I guess that the current options look at the git history, and are not able to see my uncommited changes.

Is there a way to check my changes before I commit it?
