Elm-format: Spacing between if clauses

[avh4]

Should have blank line before else clauses, as shown in the 0.17 guide:

after : Int -> Task x ()
after backoff =
  if backoff < 1 then
    Task.succeed ()

  else
    Process.sleep (toFloat (10 * 2 ^ backoff))

Cool! I've never tried coding in this style, but I appreciate the newlines in case expressions, and it makes sense that they'd be nice in if expressions as well.

I vote for no, the else feels disconnected.

What if if-else has no space, but if-else if-else if-else chains have a space? The thinking is that chains are like case, but when they're two it's just one unit.

Here are a couple of snippets:

foo =
  let
    value1 =
      if True then
        "Value 1"
      else
        "Value 2"

    value2 =
      "Value"
  in
    value1 ++ value2

And with space;

foo =
  let
    value1 =
      if True then
        "Value 1"

      else
        "Value 2"

    value2 =
      "Value"
  in
    value1 ++ value2

I get the impression that the space above else dilutes the code too much.

@mgold you mean like this?

foo =
  let
    value1 =
      if x == 1 then
        "Value 1"

      else if x == 2 then
        "Value 2"

      else if x == 3 then
        "Value 3"

      else
        "Value 4"

That actually looks pretty decent!
A variation of that could be that the last else doesn't have the empty line above it, but I wouldn't do that.

This was implemented in 0.8.0, at specific request from Evan.
