This mod will convert single enter into <br />, double into a <p> ... </p> set.
It will store xhtml in the db for display in the browser.
In the editor, none of these tags will be returned for view, but will be stripped out.
Any extra markup (h1-6, span, div, etc) will not be stripped at editor view.
NOTE: the original is not my code (I'm not that clever). Please leave the credit statement in tact.

processing()
locate
$text = clean($_POST['text']);
and make like
$text = clean(convertTags($_POST['text']));// converts various newlines (\n) to either <p> or <br />
form_articles()
in the text area for entry
this line
echo html_input('textarea', 'text', 'txt', $frm_text, l('text'), '', '', '', '', '', '2', '100', '', '', '');
to be
echo html_input('textarea', 'text', 'txt', remove_tags($frm_text), l('text'), '', '', '', '', '', '2', '100', '', '', '');
