[ELPA Syncer]

    Default to indent-relative
    
    nix-indent-function is still not ready for default. Too many bugs with
    let ... in and parameters. Help wanted! I don’t have enough Emacs
    parsing knowledge to do this. Haskell is able to get good indentation
    with a similar syntax to Nix, so I know it’s possible.
