System: NetBSD hermes.lorenz.place 8.99.1 NetBSD 8.99.1 (RPI2) #1: Sat Jul 1 14:10:03 CEST 2017 bjjl@hermes.lorenz.place:/home/bjjl/obj/sys/arch/evbarm/compile/RPI2 evbarm
Architecture: earmv7hf
Machine: evbarm
>Description:
	When changing screen resolution, and then using the history function
	of the interactive shell, the view gets screwed up.
>How-To-Repeat:
	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.

 I just reproduced it on yesterday's -current/amd64 (8.99.37) both in
 an xterm running on the machine, and sshing in. My shell is /bin/sh.

 This is not specific to tmux.  You can see that with any window
 changing size, e.g. a local xterm or ssh'ing into a netbsd machine.
