Beginless ranges and line breaks

[mvz]

This code seems to be parsed incorrectly:

def bar
  foo = 2
  ..foo
end

Calling bar returns ..2, but Parser parser this as:

s(:def, :bar,
  s(:args),
  s(:lvasgn, :foo,
    s(:irange,
      s(:int, 2),
      s(:lvar, :foo))))

I would expect this to be parser identically to

def bar
  foo = 2;
  ..foo
end

This version is parsed by Parser as:

s(:def, :bar,
  s(:args),
  s(:begin,
    s(:lvasgn, :foo,
      s(:int, 2)),
    s(:irange, nil,
      s(:lvar, :foo))))

Yes, looks like a bug, tDOT2 is emitted instead of tBDOT2 and it's reduced to a normal range
