The text looks fine, but I would like to point out one catch
which could result from placing too much emphasis on that space.
Namely, a header field consists of a header field name, a colon,
and a header field body, i.e. everything after a colon belongs
to a field body, including that [CFWS]. It would be wrong if
it could somehow be undestood that a field body starts only
*after* a space.
