User runs `ssh-wrapper example.com`
`ssh-wrapper` does:
`ssh example.com /usr/bin/env sh -c "$(cat conductor.sh)"

Where `conductor.sh` is a sh script that does something like (pseudoterminal below):

echo <control sequence to notify terminal emulator that it's in ssh mode>
run login shell as a child process through `script` on file descriptor 3
while true:
  output = [read from file descriptor 3 without blocking]
