basic_ios::fail() question


The basic_ios::fail() member function returns true if the eofbit
or the failbit is set.                                    ------

 bool fail () const { return (rdstate () & (eofbit | failbit)) != 0; }

Why the eofbit? I would expect the badbit instead.
                                   ------
 bool fail () const { return (rdstate () & (badbit | failbit)) != 0; }
