That's fast, thanks. Although looks like the help message is backwards, it should be:

Also regarding documentation, it seem to me that page_hint argument does not really exist, unlike what is written in the documentation.

Now with page_hint implemented we can update the document for consistentency.

Actually, the correct specification would be line[:column[[:page_hint]:input]], but that's way too clunky.
