Steps to reproduce

1. Run monomux -i
2. Press Ctrl+d

Expected Behavior:

Monomux handles ctrl+d elegantly (personally I would like monomux to just stop expecting any input and quit without any error code).

Actual Behavior:

Monomux gets stuck in an infinite loop and keeps printing

Monomux sessions on '/run/user/1000/mnmx'...

    1. Create a new session (/bin/fish)
    2. Quit

Choose 1-2:
ERROR: Invalid input
