Article::showArticle (to update some link tables or something) which
redirects the user.
Article::quickEdit does not do a proper edit.
The Article::showArticle link-table-updating parts should be moved to
Article::cleanupUpdateArticle or similar. The redirect parts should be moved to
after wherever Article::updateArticle is called (probably only EditPage.php)
I am willing to do this myself, but of course anybody else's patch would be nice.
