[tcpm] Additional editorial comments on draft-ietf-tcpm-rfc793bis-20

[Gorry Fairhurst <[e-mail]>]

I did some very careful reading of a few sections of  rfc793bis, and 
have additional some late editorial comments.

I suspect these really are minor, but I'd hope worthwhile:

---

(1a) The text uses /may not/, in these two places:

/Note that some options may not be included on all segments/

- I wonder if this is umambiguous to all English speakers (it's not so 
clear to me), I think it could be better as

/Note that some options might not be included on all segments/

or ...

/Some of the segments might not include include all options/

... of something like that this?

---

(1b) I'd suggest similarly avoiding /may not/ in the description of IP 
Option processing.

---

(2) The document seems to be missing an IPv6 "view" of extensions in the 
IP Options part, section 3.6.1 (This is mentioned in the pseudo-header 
compuation). I suggest we add a brief sentence saying the calculation of 
"IPv6 Extension Headers" follows thar for IP Option size.
