/*! \brief Opens a new page from a file.
* \par Function Description
* This function opens the file whose name is <B>filename</B> in a
* new PAGE of <B>toplevel</B>.
*
* If there is no page for <B>filename</B> in <B>toplevel</B>'s list
* of pages, it creates a new PAGE, loads the file in it and returns
* a pointer on the new page. Otherwise it returns a pointer on the
* existing page.
*
* If the filename passed is NULL, this function creates an empty,
* untitled page. The name of the untitled page is build from
* configuration data ('untitled-name') and a counter for uniqueness.
*
* The opened page becomes the current page of <B>toplevel</B>.
*
* \param [in] w_current The toplevel environment.
* \param [in] filename The name of the file to open or NULL for a blank page.
* \returns A pointer on the new page.
*
* \bug This code should check to make sure any untitled filename
* does not conflict with a file on disk.
