When we go to links such as:

http://pt.wikibooks.org/w/index.php?action=edit&preload=Project:About&title=MediaWiki:test
we note that both "test"and "MediaWiki:test" doesn't exist. But using the
preload parameter for the first page we get the text "#REDIRECT [[wikibooks:Sobre]]"
preloaded although for the second we don't.
