requires empty space after string concat operator

[trylika]

applies to 2+ verison, with following code, strict standard requires empty after first line:

            $a .= 
                '<tr>' .
                '</tr>';

Standard complains about new line after .=. This code is valid:

$a .= '<tr>' .
    '</tr>';

Does this still needs to be fixed?

[trylika]

when there is a lot of string content to be fitted into variable, it looks ugly when writing in the same line, thus no, such solution does not fix this problem.
