a code: 
                <?php 
                echo "ahoj".
                $sf_content.
                "ahoj"; 
                
                ?>

if you press enter after . then the carret jumps to the beginning where it should continue like you were typing a new command. it should be intended in the same way as multi-line expressions are indented after fix . 

Formatting works well.  

                <?php 
                echo "ahoj".
                       $sf_content.
                       "ahoj";
                ?>
