Subject: [PATCH] Add multi-line comments for Elm (#283)

Technically the minimum necessary syntax for block comments requires
only a single hyphen (`-}`, `{-`), but I have found that using a double
hyphen plays a bit more nicely with the elmcast/elm-vim auto-formatting.
Further, uncommenting when using the single dashes leaves an extra level
of indentation (again, when using elmcast/elm-vim).
