when last command had no \n... should I discard it?
Ideally, I should remember the part and wait for next
read() to get the rest up to a \n. But that can go
to infinity. Too long commands too quickly are just
bad. Cannot/Won't change that. So, discard the unfinished
command and have fingers crossed that the rest of this
unfinished one qualifies as "unknown".
