I think 1/10 and 2/10 are the other way around. Preferably, these
would be three patches, in this order:
(1) prepare the "formatting state" and pass it around; no other
code change.
(2) have "color" use that facility.
(3) add a new feature using that facility.
The first two may want to be combined into a single patch, if it
does not make the patch too noisy.
