Chaining semantics after arguments with outdent

[xixixao]

After adding chaining syntax in #3263 there has been a problem that kept bugging me:

callA callB ->
  body
.method()
# and
callA callB -> body
.method()
# Compiles to:    callA(callB(function() { return body; }).method());

but

callA callB expression
.method()
# Compiles to:    callA(callB(expression)).method();

This fixes the issue and makes functions and objects behave as any other argument.

👍 Really feels more natural that way

This begs the question: should whitespace before member access always close implicit calls/objects a la Coco/LiveScript?
