Possible typos

Hi,

Here are a few remarks to improve the document.

In 2:

    Transports for Netnews articles MUST treat news articles as uninterpreted
    sequences of octets, excluding the values 0 (which may not occur in Netnews
    articles) and 13 and 10 (which MUST only appear in Netnews articles as a pair
    in that order and which together denote a line separator).

Wouldn't it be better to write %x00, %x0D and %x0A?
"and 13 and 10" -> not ", 13 and 10"?



In 3.3:

    Such a history database would grow without bound, however, so it is common
    and permitted to optimize based on the Injection-Date or Date header field
    of an article as follows.

"to optimize it"?  (I do not know whether "it" is mandatory or not in English there.)



In 3.6, the Injector-Info: header is mentioned.  Isn't it Injection-Info: instead?



In 3.9:

    the leftmost unapproved newsgroup is is the leftmost moderated newsgroup
    in that field

Only one "is".


    Any Path header field MUST either be removed or truncated to only those entries
    following its "POSTED" <diag-keyword>, if any.

Is it clear enough?  "following" and not "preceding"?  It depends on the direction
we read the Path: header :)



In 3.10.2:

    there is no one "official" gateway

Is "one" correct here?  (Probably yes, but better ask.)

What if Original-Sender already exists?  Is it renamed to X-Original-Sender (as 3.10.4
seems to suggest)?
