If that helps, magit only uses `start-file-process` and never `make-process`. > There are lots of different use cases, and no single correct answer. For example, when running M-x shell, I probably want SSH prompts and am willing to accept a brief blocking wait, but not when starting a Flymake backend process. I don't think there's a real difference between start-file-process and make-process, though; make-process is newer and more powerful, but it's not a conceptually different thing.
