In a PHP file, if I have code like this:
$cmd = new DBCommand('SELECT * FROM `Group`');
$results = $cmd->query();
and I select part of the SQL string and press Ctrl+/ to comment the line out, instead of the regular PHP comment (//) I get an SQL comment (--). Oddly, if I make a selection that starts in the SQL string and ends outside of it, then press Ctrl+/, nothing happens.
