return true, with comment stating a return false...

Ok, not exactly as the title implies, just wanted to get some of your attention

Function get_parent() states that it echoes a page's parent slug as a String. The problem is that the $parent var is an object, so if I just want the echo for that object PHP will call the __toString method but if I want the function to return the slug I get an object instead of a string.

For example:

get_parent() will echo the parent's slug.
get_parent(false) will return an object.

The behavior doesn't match the documentation and I think that it should really return a String and not an object.

I noticed this when doing a simple if(get_parent(false)), which is always true, even if the page has no parent.
