Another bug in anonymous mode.

Here another bug: As anonymous user you can commit a file as a patch and when you do that, it ask you for your E-Mail for if you want to be notified when the patch will get approved or rejected. As a SVN user you can approve the patch and it ask you if you want to send an E-Mail to his author. Because the E-Mail field is optional you should only be asked to send an E-mail if the user added his E-Mail address. I tried to reject or approve a patch, with E-Mail on it and It doesn't work. It shows an infinite loop 'Saving data'. I tried to reject without E-Mail and it loops again but if you refresh the page the file got rejected. Thanks -- Yago Ferrer
