Hooks used ArticleViewRedirect OutputPageBeforeHTML
Check usage (experimental)

Note: Redirecting to section is now available as a core feature, so this extension is deprecated.

I basically ripped this off of something I read in the Bugzilla, but cleaned it up a touch to be compatible with m:User:Emiller/GoogleMapsExtension. This extension allows #REDIRECT directives to point to particular sections of articles, e.g. #REDIRECT [[Games#Broomball]]. It uses JavaScript, so it won't work in ancient web browsers. Anyway, paste this into extensions/RedirectAnchor.php:

 <?php
 
    $wgHooks["ArticleViewRedirect"][] = 'wfRedirectJump';
    $wgHooks['OutputPageBeforeHTML'][] = 'wfRedirectInjectJS';
 
    function wfRedirectInjectJS(&$parser, &$text) {
        global $wgRedirectAnchorInjection;
        if ($wgRedirectAnchorInjection) {
            $text .= $wgRedirectAnchorInjection;
        }
    }
 
    function wfRedirectJump (&$array) {
        global $wgHooks, $wgRedirectAnchorInjection, $wgJsMimeType;
 
        $section = $array->getTitle()->getFragment();
        if($section) {
            $inject = "<script type=\"{$wgJsMimeType}\"><nowiki><!--\n//<!CDATA[\n"
            ."window.location.hash = '".preg_replace("/%/", ".", urlencode($section))."';"
            ."\n//-->\n</nowiki></script>\n";
            $wgRedirectAnchorInjection = $inject;
        }
        return true;
    }

And then add this to LocalSettings.php:

require( "extensions/RedirectAnchor.php" );
