Comment (by toscho):

 Replying to [comment:5 SergeyBiryukov]:

 result is not intuitive though.

 But that is not true: if `<!--nextpage-->` is at the first position,
 paging does not work. You get the content of all pages on one page,
 because the comparison …

 {{{
 if ( strpos( $content, '<!--nextpage-->' ) )
 }}}

 … is not strict enough. There is even a
 [http://www.php.net/manual/en/function.strpos.php big red warning] on the
 manual for that behavior:

 > This function may return Boolean `FALSE`, but may also return a non-
 Boolean value which evaluates to `FALSE`. Please read the section on
 Booleans for more information. Use the `===` operator for testing the
 return value of this function.
