tmux/input-keys.c
Tiago Cunha 215ee46106 Sync OpenBSD patchset 896:
When mode-mouse is on (it is off by default), automatically enter copy
mode when the mouse is dragged or the mouse wheel is used. Also exit
copy mode when the mouse wheel is scrolled off the bottom. Discussed
with and written by hsim at gmx dot li.
