deadly sharp w_class 1 fix

fixes #5550, where embedded items with w_class = 1 would be impossible to be yanked out,
leading to certain death should the victim not get one full surgery procedure per item.
most notoriously forks as they were sharp, common and unyankable prior to this.
also fixes double "the" in message.
thanks to @Zuhayr and @mwerezak for their feedback on this issue.
