It should not silently truncate.

I think it should return a syntax error.

Well, not "great skill" per se, but additional effort.  I can't see why
it would be worthwhile.

Draft 15 does not say what happens if a client violates the line length
limit.  There are three things a server can reasonably do:
- accept the longer command
- silently truncate to 512
- return a syntax error

Do we intend to comment on which of these are appropriate?
