Fine by me.

Fine by me.  As I said, I won't argue this anymore; we'll just do what we must.

Given the strength of the wording in all the previous RFC's, I don't think
the function should be piggy-backed on list.  I think another command is
the right thing to do; it's less hassle for everyone.

It's clear that the first line of the body is line 1.  It's not at all
clear (and private mail from some time ago confirmed that Marshall didn't
believe) that asking for 0 lines of the body is supposed to be out of
bounds.

However, since there are servers that barf on 0, clients should use 1, not
0, if they want headers.  Whether that means we codify 1 into the RFC, or
add a warning, or just ignore the issue, I dunno.  Like you said, no big
deal.

I think requiring accuracy provides no functionality, and carries with it
not insignificant resource expense for some servers.  But I understand the
reluctance to allow cheating in the RFC.

Let's leave it the way it stands; do not put in language to allow
approximation, but neither add language that makes it seem that to-the-byte
accuracy in those numbers is a matter of life or death.

This amounts to a small wink at server authors who are challenged in this
department.

I support that.
