This is a function you can either execute once, interactively, or stick in config.fish, and it will do the right thing. Some options are included to choose some slightly different behavior, like setting $PATH directly instead of $fish_user_paths, or moving already existing components to the front/back instead of ignoring them, or appending new components instead of prepending them. The defaults were chosen because they are the most safe, and especially because they allow it to be idempotent - running it again and again and again won't change anything, it won't even run the actual `set` because it skips that if all components are already in. Fixes #6960.
