Remove some changes, at least one false positive.

These are all correct and represent better style than the previous code. It won't change the semantics of the code even on architectures where a null-pointer has bits set because comparison to or assignment to 0 is special in 'C'. Since it improves the style, and doesn't change the semantics, this is a good change.

271	Maybe '\0' instead of NUL?

271	Hmm.. I thought I had reverted this change. Yes, thanks! '\0' should work. I will commit it after testing.
