bin/52359: Command line editing broken in tmux
>Synopsis: Going back in history screws up terminal view in tmux
>Arrival-Date: Sun Jul 02 11:15:00 +0000 2017
>Originator: Benjamin Lorenz
>Release: NetBSD 8.99.1
System: NetBSD hermes.lorenz.place 8.99.1 NetBSD 8.99.1 (RPI2) #1: Sat Jul 1 14:10:03 CEST 2017 firstname.lastname@example.org:/home/bjjl/obj/sys/arch/evbarm/compile/RPI2 evbarm
When changing screen resolution, and then using the history function
of the interactive shell, the view gets screwed up.
1. Start tmux. Enter one command, say, `uptime'.
2. Enlarge or shrink the terminal window vertically
(change the number of lines the terminal window can display)
3. Press `cursor-up' key to get back to the last command
4. You will see the prompt being displayed twice; in my case
it looks like "hermes$ hermes$ uptime".
Especially for commands that span over two lines, this is highly
confusing and annoying. Cross-checking with NetBSD 7.1, this
problem does not exist yet.
