Revert "Warn users when overriding methods (via let, def or define_method) in the same example group."
Created by: myronmarston
This reverts the lib and spec pieces of e072e535.
The warning is overzealous. After upgrading a project to RSpec HEAD, I
got spammed with tons of warnings of situations that weren't actually
problematic. For example, it's common to define a let
in a shared
context that provides a default value, and than to purposefully override
that in a host group where the shared context is included. We shouldn't
warn in such a situation, but this did warn.
See #1903 for the original code this reverts.
