Where == str_replace( '$1', $wgMetaNamespace, $namespaceNames[NS_PROJECT_TALK] ) === $wgMetaNamespaceTalk, remove the entry in $wgMetaNamespaceTalk

In most/all cases, these should match, and hence, the explicit entry is unneeded.


Similar can be also said for $wgMetaNamespace, which if it's the same as $wgSitename, it isn't necessary.

/**
 * Name of the project namespace. If left set to false, $wgSitename will be
 * used instead.
 */
$wgMetaNamespace = false;
