As it is now, us convert-tabs-to-space types cannot use this. Not that 
I'm dying for it anyway, I'm all for unnesting nested code, but it's a 
nice idea still.

In fact, I'm a little curious to see it, could you please post a 
screenshot on a webserver of how it looks there for us lazy to test it 
on our own systems?
