Jack Nagel 1b0f0824fe Requirement: env DSL is evaluated in context of self, not ENV
This was meant to support:

  env do |req|
    append_path 'PATH', req.some_method
    ...
  end

i.e., the block was evaluated in the context of ENV. But it turned out
to be not so useful after all, so I'm ripping it out before something
actually depends on it.
