Issue:
Last tag always has \n in the description
Hi,

the `unwrap: true` option fails to strip the last new line before `*/`, so an empty description on the last tag in the comment always becomes '/' (not sure why) and a non-empty description always has a newline at the end.

In my code, I have to do this to remove spaces/newlines from before the end of the comment, before passing the comment to doctrine.
     
     comment = comment.replace(/[\s\n]*\*\/[\s\n]*$/, '*/');


Thanks

Fixes #87.

Not sure if this is the best fix so open to suggestions.
