Comment 2 for bug 790971

Are you sure this ever worked? I certainly never documented this syntax; the trailing colon is out of line with the rest of the syntax; and it partially duplicates the 'credentials' field added by Loïc to handle the 'C' flag.

I would recommend deleting the 'flags:' line and using the documented 'credentials yes' line instead. If you need the 'O' flag, I'd be happy to add support for 'open-binary yes'.
