No way to break a line at an operator

DCS gives me no way to break a long line at an operator. Pretend that

  $foo = $bar + $baz;

is too long. According to http://drupal.org/coding-standards#linelength I should try to keep most lines under 80 characters. I usually break after the operator:

  $foo = $bar +
    $baz;

but PAReview.sh complains that | ERROR | An operator statement must be followed by a single space. My reading of the Drupal coding standards is that a newline should count as a space, but I am willing to take Code Sniffer's advice. So I tried

  $foo = $bar
    + $baz;

Now, I get the message | ERROR | There must be a single space before an operator statement. This seems stricter than the advice at http://drupal.org/coding-standards#operators ("single space" instead of "a space") but again I am willing to go along. However, I think an exception should be made for multiple spaces at the beginning of a line.
