If it turns out, that I'm using the whole day on removing malicious category
links, I'll think about another solution :-)

I guess it works more like 1. grabbing all the wiki text, from DB _and_ from
the user's edit form, then 2. pass it to the parser. That's why a check of
the access rights in a function that only grabs from DB isn't sufficient...

Yes, that's the key. The very last action of index.php is to call
$wgOut->output(), so I copied my (slightly modified) quickhack code to this
function and it seems to work.
So we got three places to modify:
includes/Title.php prevent access for default view, editing, diff
includes/OutpuPage.php prevent access in case of preview of templates
LocalSettings.php define access rights
includes/OutputPage.php, line 370 (function output() at the beginning):
# inserted by m:o
// get categories as array
$parentCategories = $this->getCategoryLinks();
if( !empty($parentCategories) ) //prevents php warning for uncategorized pages
// go through all categories wich have restrictions
foreach( $wgRequireUser as $category => $requiredUser )
// go through all categories to which a page belongs to
foreach( $parentCategories as $key => $siteCategoryLink )
// is the page in a category that is restricted?
// strip_tags gets rid of the <a href...>
if( $category==strip_tags($siteCategoryLink) )
// ...then check, whether the user is the right one!
$user = $wgUser->getName();
$isUsrAllowed = preg_match("/\b$user\b/", "$requiredUser");
// not the right one? -> go away!
if( $isUsrAllowed!=1 )
// don't show any categories on the 'login required'-page
$this->mCategoryLinks = array();
$this->mBodytext .= '<br><br>Wenn du von einer Bearbeiten-Seite hier
