cannot omit @private in the docs

[timaschew]

It seems that the behavior was changed, because I found some issues that was fixed.

But for now it doesn't work anymore, but the documentation tells something different:

--private, -p Show privates [default: false]

This options is ignored, it's always the same result: The methods have a private tag.

In the source code I don't see any conditions for this private option.

Please include the patch/fix. Would like to use this documented switch to create private and public documentation.
