Emacs mode: Incorrect syntax highlighting of **/

Hello,

The Scala emacs mode incorrectly highlights commends ending with **/.
The rest of the buffer (or the text till the next comment) will have
the comment-face. E.g.

/**
* This will break everything
**/
class Foo {
blah
}

I took a look at the code but couldn't work out where the syntax
highlighting for comments was actually performed.

Thanks,
N.
