But code does this sort of thing -- for instance, Message allows headers
to be specified in various ways, but will run the header names trough
`capitalize'.

So this isn't just about doing comparisons, but separating out text
transformations that are done according to a protocol specification
(i.e., octets that happen to be ASCII) vs. the normal DWIM text
transformations.
