Comment(by azaozz):

 Heh, the phpdoc there is really wrong. They look a lot better in 1.5 than
 now. Don't even need two args, one arg would work fine and will make them
 more compatible (if they only echo the string). Perhaps we need to revert
 then.

 {{{
 function checked($arg) {
   if ( $arg )
     echo ' checked="checked"';
 }
 }}}
 used like:
 {{{
 checked( get_option('blah') );
 }}}
 or
 {{{
 checked( $blah === 0 );
 }}}
