Allow expression break after open paren

[mdr]

Ported from issue #32:

Thank you for explaining, it's not an urgent need, but it would be nice if it were supported at some point. If you want to fix individual cases, then my biggest pain point is scalariform moving:

(
  a_long_line &&
  b_long_line
)

to

(a_long_line &&
   b_long_line)

which I find notpretty at all...

Would that also include the following?

case class Foo(
  bar: String
  baz: Int
)

Currently the line break for the close parenthesis is swallowed:

case class Foo(
  bar: String
  baz: Int)
