TSDocEmitter emits @defaultValue in a weird way #426

When parsing a comment like this:

/** @defaultValue value */

and printing the parsed docComment using TSDocEmitter it will create this output:

/**
 * @defaultvalue
 *
 * value
 */

While this seems to be still working with IDEs it is quite ugly.

I think this can be fixed by using the same handling as with @returns.
