Bug#4388: emacs mail-mode fails RFC822 section 3.4.7
I'm using Emacs under X and font-lock mode is turned on. If you write
`cc:' or `Cc:' in the headers it appears in black (or the default
face); however if you write `CC:' then it appears in purple.
However, RFC822 headers are case-independent, so it should be the same
colour independent of letter case.
