There is a problem when there is an empty line in T_COMMENT within a function call with function parameters being multiline. Consider this code for an example:

foo( $a, /* $c, $d, */ $e ); 

I would expect the sniff to leave the empty line intact, however, it removes the empty line and even indents the code incorrectly after doing so. So, the code after running the sniff would look like this:

foo( $a, /* $c, $d, */ $e ); 

I can fix this problem, if someone can confirm that this is in fact a bug and not a "feature" :)
