Input

→ View on rubyfmt.run

if foo
  .bar
end

if foo < bar
  .baz
end

if foo = bar
  .baz
end

Output

if foo
    .bar
end

if foo < bar
      .baz
end

if foo = bar
    .baz
end

Expected behavior

I expected 4 spaces. I couldn't find any indication in the rubyfmt source that this is intentional.
