Description

podman-remote run and podman-remote start --attach does not handle detaching with the detach keys <ctrl-p><ctrl-q> correctly.

Steps to reproduce the issue:

For podman-remote run:

1. Start the podman service

2. podman-remote run -it alpine sh

3. detach with <ctrl-p><ctrl-q>

For podman-remote start --attach:

1. Start the podman service

2. podman-remote create -it --name test alpine sh

3. podman-remote start --attach test

4. detach with <ctrl-p><ctrl-q>

Describe the results you received:

The process does not exit.

Describe the results you expected:

The process should exit with exitcode 0.

Additional information you deem important (e.g. issue happens only occasionally):

With podman-remote start --attach the error happens only if the container is not already started.
It also works fine with podman-remote attach

If I hit enter after detaching I get this error: ERRO[0003] failed to write input to service: write unix @->/run/user/1000/podman/podman.sock: write: broken pipe
So it looks like it does detach and closes the pipe but the process does not exit. It instead waits for the container to exit.
