OK, because you no longer put PREFIX in outbuf, outbuf.len becomes
an easy way to tell if we have anything accumulated, and if there
already is something, we separate our message from it with a LF.
I like the simplicity and clarity of the logic.

Likewise for all other changes.

... and this does make sense.
Lukas, can you see what is in 'pu' after I push out today's

result of the SQUASH??? change?
Thanks.
