[wp-hackers] newlines from rich text editor do not convert to paragraphs

[Davit Barbakadze]

Probably it would have been more logical applying filters attached to
'the_content' hook within get_the_content() function. This way we
could get filtered content echoed via the_content() tag, filtered
content in a string via get_the_content() and pure content via
$post->post_content.
