Bug #18890: parse.y: pattern label is newline-sensitive if it is dynamic

[qnighy (Masaki Hara)]

The two patterns in the code below behave differently:

def f(obj)
  case obj
  in foo:
    0
    true
  in "bar":
    0
    true
  else
    false
  end
end

p f({ foo: 42 }) # => true
p f({ bar: 42 }) # => false

which does not seem an intended behavior.
