The recent change to switch `psub` to use `argparse` caused it to use a fifo by default because it inadvertently fixed a long standing bug in the fish script. This changes the behavior back to `psub --file` being the default behavior and introduces a `--fifo` flag. It also updates the documentation to make it clearer when and why `--fifo` mode should not be used. Fixes #4222
