I guess these two are more or less equivalent.
I view "outbuf" more as "holdbuf", i.e. the payload that has been
received and yet to be shown, and from that point of view, having
and keeping PREFIX which is not something we received in there while
looping to grab more input makes me feel dirty. IOW, I consider
"empty" is the correct base state of the hold buffer before anything
happens.
I understand that you view "outbuf" as what has been prepared to be
shown but not ready to be shown due to lack of LF, and from that
point of view, the base state of the out buffer before anything
happens could be "it has PREFIX and nothing else".
It's just that if you take the latter, then the conditional after
the loop exits (i.e. the last transmission was an incomplete line)
cannot be "is outbuf empty?", as your base state is "has PREFIX and
can never be empty". I was working back from that if statement.
