`Alt+Q` destroys file, can't fix with undo

[Erik Weitnauer]

If in javascript I place my cursor in a comment like this:

/** My custom styled comment with
 * two lines. */

and press Alt-Q, everything in the file up to the comment gets deleted. Even worse, when I use the undo function, I go back to a state with my whole file again, but the comment destroyed.

Please either support the above more concise style of writting block comments, or don't work on them at all. Destroying the file without a way to undo the change is a serious show-stopper.

Other than this I love the plugin!
