Subject: [PATCH] Compatibility fix for block arity changes in Ruby 1.9.

The behavior of #call on lambdas and procs is now different:

  > Proc.new { }.call(self)
  => nil
  > lambda { }.call(self)
  ArgumentError: wrong number of arguments (1 for 0)

This patch adjusts BlockValueContainer to compensate.  For more
