Juan found another small nit, so please do send a v12.  He liked (with
the small change in cancellation) your last three patches, so there is
no need to split out patch 13 (as you had it in v10).

Do those few lines of code change the protocol?  If yes, I'll go against
all my previous recommendations and suggest a #define.  If no, it is
fine to leave it for later, but I would still suggest posting the patch
on the list just for information.
