Description of problem: The mediawiki postinstall scriptlet runs mw-updateallinstances.  That script in turn runs mw-createinstance for
each path in /etc/mediawiki/instances (i.e. /var/www/wiki).  And the
mw-createinstance script creates a bunch of symlinks, including one for
redirect.php.  But /usr/share/mediawiki/redirect.php is no longer in the
rpm, so this is a dangling symlink.  According to the HISTORY file,
redirect.php was removed in version 1.22, since it was unused.


Version-Release number of selected component (if applicable):
mediawiki-1.23.2-1.fc19.noarch


How reproducible: Install or upgrade the mediawiki-1.23.2-1.fc19.noarch rpm.
Notice the dangling symlink.


Steps to Reproduce:
1. rpm -U mediawiki-1.23.2-1.fc19.noarch
2. ls -l /var/www/wiki/redirect.php
3. wc /var/www/wiki/redirect.php

Actual results:
bash-4.2$ ls -l /var/www/wiki/redirect.php 
lrwxrwxrwx 1 root root 33 Aug 27 08:42 /var/www/wiki/redirect.php -> /usr/share/mediawiki/redirect.php
bash-4.2$ wc /var/www/wiki/redirect.php 
wc: /var/www/wiki/redirect.php: No such file or directory



Expected results: The invalid symlink should not be installed.
