Signals are not handler properly

[nadejin]

My term is completely broken after finishing application with SIGINT/SIGTERM (cursor and input characters are invisible, x axis positioning is broken too), I guess these signals should be handled to terminate resources properly.
I'm using Arch Linux and termite terminal emulator.

Yup, tui programs almost always need to install signal handlers.

Run stty before and after to find the diff.

Quick fix is reset.
