Btw, faster:

$string = preg_replace('/\r?\n/', chr(10), $string);
$string = preg_replace('/\r/', chr(10), $string);

>  		$theLines = explode(chr(10),$string);	// Split lines

$theLines = preg_split('/\n/',$string);

$newVal = preg_replace('/\x20$/m','=20',$newVal);
$newVal = preg_replace('/\t$/m','=09',$newVal);

return preg_replace('/\r?\n$/D','',$newString);

Generally, preg_* are faster than ereg_* or other string functions.

You do not have to include it all in your patch but if you do, it will
be better.
