A message that is too long for one packet now goes out as up to
message_parts_max parts (default 3, 1 turns it off), each ending with
its part number: [1/3], [2/3], [3/3]. Each part, with its part number,
fits in the byte limit of the conversation (130 for a channel, 150 for
a direct message). A cut goes at a space, and a word with no space to
cut at is cut between characters, never inside an emoji sequence or
after a combining accent.
Channel parts wait the transmit cooldown between them, so that the
floods do not go out as a burst. A direct part waits for the
acknowledgement of the part before it, or the end of its wait. An
unacknowledged part still lets the rest go out, and ^R retries each
one. A hard failure stops the rest and puts their text back in the
compose line. The byte gauge shows the number of parts and the bytes
of the last part. Rooms are not changed.
