the_content() contains unexpected hard coded string replacement

[awelzel]

In wp-includes/post-template.php the function the_content() has an unexpected string replacemenet:

function the_content( $more_link_text = null, $strip_teaser = false) {
	$content = get_the_content( $more_link_text, $strip_teaser );
	$content = apply_filters( 'the_content', $content );
	$content = str_replace( ']]>', ']]>', $content );
	echo $content;
}

This makes no sense at all and breaks CDATA blocks. Why?

Suggested solution: Remove the line

	$content = str_replace( ']]>', ']]>', $content );

and implement a filter to do this replacement where neccessary.
