bug#2772: 23.0.91; emacsclient loses keybindings after terminal suspend/resume under screen

[Jakob Krainz]

When I start "emacsclient -t" under GNU screen,
then suspend it (with C-z) and resume again, it stops
understanding the arrow keys.

Instead it starts echoing error messages like
M-[ b is undefined

The value of $TERM is:
$ echo $TERM
screen
