Searching for inline file references and attaching local files are not working with current pear Mail_Mime module from git

There is problem in file mailmime.inc with extending Mail_mime class from https://raw.githubusercontent.com/pear/Mail_Mime/master/Mail/mime.php - current class realization does not has the _htmlBody property, but this property is using in the get method.

public function &get($params = NULL, $filename = NULL, $skip_head = FALSE) {
    if (isset($this->_htmlbody)) {
      $this->_htmlbody = preg_replace_callback(
        array(
          ...
        ),
        array(&$this, 'attachRegex'),
        $this->_htmlbody
      );
    }
    return self::successful(
      parent::get($params, $filename, $skip_head)
    );
  }

The good news is that class has two interface functions - getHTMLBody and setHTMLBody, so we just need to use them instead of protected property (which now is called simply htmlBody).

 public function &get($params = NULL, $filename = NULL, $skip_head = FALSE) {
    $sBody = $this->getHTMLBody();
    if (!is_null($sBody)) {
      $this->setHTMLBody(
				preg_replace_callback(
					array(
						...
					),
					array(&$this, 'attachRegex'),
					$sBody
				)
      );
    }
    return self::successful(
      parent::get($params, $filename, $skip_head)
    );
  }

With this modification class should work with both old and new (git) version of Mail_Mime pear module.
