When a user add a new section without summary and have the option "Prompt me when entering a blank edit summary" activ, he get a unknownerror.

<?xml version="1.0"?><api><error code="unknownerror" info="Unknown error: ``226&#039;&#039;" /></api>

Looks like EditPage::AS_SUMMARY_NEEDED is not handled in ApiEditPage.

Please add a better error text.

Thanks.
