Actually..

This is the fancy T5 after all :)

Does someone want to create a HTML/Pretty Printer ( htmlTidy ), mixin?
Or MarkupRendererFilter?  That should probably help our debugging even more!

I guess I would love to turn that on during dev, then decide to turn it
on or off afterward. (maybe with a runtime property controlling that).

But yes the whitespace matters for some browsers sadly.. Though it has
been a long time since we've had to deal with that in our shop.  So I'm
not sure what's different, maybe I'm using HTML strict or something..
I wonder if there is a pattern, we can make a MarkupRendererFilter to
just magically take care of it for everyone as well.
