Tristan,
	Your instinct is good, but Tao is right, every commit has to
compile and work.  The next patches you work on, keep trying to break it
up into logical things, but have working code.  One of the best tricks
is doing the isomorphic changes (changes that don't actually affect the
behavior yet) first.  I use this trick a lot.  I can add an argument to
a function or change what is passed through without actually changing
the functionality.  Once I've used this methodology to restructure the
code, then I can change the behavior.
	For this particular change, I'm OK with it being one patch as I
stated in my other email.

Joel
