Fix broken line break output when running via docker compose v2.2.x

[defunctl]

Since upgrading to the new docker compose binary (running v2.2.2 on my system), line break outputs have been broken when docker compose exec is run. GitHub Issue, work around

Before this bugfix:

After this bugfix:

I tested it as well with docker-compose, which is running v2.17.2 on my system and this didn't change the output either way, so it seems backwards compatible.

I also tested running with docker compose exec -T but that didn't make a difference either way, with or without the trailing ' </dev/null'.

I'm not sure this fix would be compatible with Windows in an environment like Powershell.
I had no time to test this out, but it should be tested there too.
Slic only requirements are Docker and PHP and it should run on a vanilla Windows terminal.
To handle the Windows env, the fix could check whether the DIRECTORY_SEPARATOR is \ or not.

I've tested this out locally and the fix is introducing issues:

With the fix, with slic debug on:

With current main, with slic debug on:

I've pushed a fix to try and apply the fix more selectively.

Thanks, I just assumed everyone was using WSL2 these days. Do note that the bug itself is only when running docker compose exec, so commands that ultimately execute inside the container.

Your screenshots are just the docker compose output. I pulled down your changes and the bug is once again there:

slic dc exec slic "ls -al"

Tested again and it's all working correctly now.
