Actually, I forgot to also mention that the browser is changing the
control-M (^M) from the query when it sets the default value for the
textarea to "<br />". I guess that is the HTML representation of the
^M.

I'm currently using:

$_POST[$field] = str_replace("\r\n", "\n", $_POST[$field]);
$_POST[$field] = strip_tags($_POST[$field], '<br />');

in a foreach loop for all the $_POST vars, but it's still not removing
it.
