^_^ sorry wt was an accident... Thought I was using et... I can't 
clearly remember how long I've been up... But I know I'm sleepy enough 
that I don't feel like digging through my IRC log to find out when I got 
on...
That note on $wgDBprefix is a note on the different level of prefixing.
We prefix tables with $wgDBprefix so that they don't interfere with the 
tables for another wiki or other software using the same database.
The idea of prefixing an extensions table is so that it doesn't 
interfere with future tables added to the MediaWiki software or in other 
extensions.
But MediaWiki tables, don't interfere with MediaWiki tables, because 
there is only one type of MediaWiki software by one group, unlike 
extensions which are partly made by people outside of the software,  and 
outside of communication with most others doing the same. So we don't 
add a wt prefix to the actual MediaWiki tables.

So we end up with:
For core tables: $wgDBprefix . tableName
For extension tables: $wgDBprefix . 'et' . ExtensionName . TableName
