javascript comments

[Perry Smith]

I'm tryimg to use JSDoc and it likes to have the comments look like this:

/**
 * hello there
 */

But when I have auto fill set and just start typing I end up with this:

/**
 * This is a sample of what I see when I start typing a comment and I */
 /**have auto fill set.
 */

I'm using emacs 23.3 with the js.el file that come with it.  I've just started
looking at the source but was curious if someone might now off the top 
of their head how to get emacs to wrap with:

/**
 * This is a sample of what I see when I start typing a comment and I
 * have auto fill set.
 */

Thank you,
