Well, it was on the TODO list and people complained while porting their
MySQL applications. We clearly made a mistake in the initial
implementation.

The question is do we fix it or continue with a different
implementation. Because we have the separate LIMIT and OFFSET we can
fix it while giving people a solution that will work for all versions.
If we don't fix it, all MySQL queries that are ported will be broken.

I assume it got on the TODO list because fixing it was the accepted
solution. We can, of course, change our minds.
