[Mediawiki-l] Setting which boxes are checked by default for block user

[Dan Nessett]

When a sysop needs to block a user using Special:BlockIP, there are boxes 
that control optional behavior. One of these is "Automatically block the 
last IP address used by this user ...". This always is set by default on 
our wiki (we are using 1.16.2). We want to have this unset by default.

I have looked around for any configuration settings that would allow us 
to deselect this option by default (e.g., http://www.mediawiki.org/wiki/
Help:Blocking_users) but have found nothing. Is there a global that 
controls this or perhaps some other configuration setting?
