Figure out if a executed statement spans multiple lines

[ionelmc]

Here's an annoying example of the problem:

         checkers/variables.py:729   call          @check_messages(*(MSGS.keys()))
         checkers/variables.py:734   line              stmt = node.statement()
         checkers/variables.py:735   line              if stmt.fromlineno is None:
         checkers/variables.py:739   line              name = node.name
         checkers/variables.py:740   line              frame = stmt.scope()
         checkers/variables.py:744   line              if (is_func_default(node) or is_func_decorator(node)

The function definition is not shown.
