Parser::C Document-attr is broken

i am using this in a C++ file

``` C++
/* Document-attr: y
 * returns the y value of Point.
 */
```

but in the HTML result it shows */ at the end in an extra `<p>` section and the lines before are threaded like `<li>` elements and i cant remove it

also the examples in RDoc::Parser::C looks like broken C++ code
