Hmm, well, I went back to make sure and found that the bozo pattern used in a
normal did shift with phase*clock.  It wasn't very noticeable so I guess I
overlooked it since I was doing both the pigment and the normal.
I tried 'wrinkles' too and it didn't work with phase*clock, but that's mentioned
in the Doc anyhow and I had tried using it without success in the past anyway.
Here's the relevant part of the Doc:

"The frequency and phase modifiers have no effect on block patterns checker,
brick, and hexagon nor do they effect image_map, bump_map or material_map. They
also have no effect in normal statements when used with bumps, dents, quilted or
wrinkles because these normal patterns cannot use normal_map or slope_map."

Sorry if I confused anyone about 'bozo'.  The quick and tiny test I did wasn't
showing it in motion before.  No wonder I'm never sure of anything.
