 commit 0d6529f669104b6f22049d456a9600d949a09018
 {{{
 Author: Simon Marlow 
 Date:   Wed Oct 19 11:46:20 2011 +0100

 delete shadowed entries from tcg_rdr_env (#5564)

 This just tidies up the out-of-scope error messages in GHCi by not
 suggesting some names twice.

 From a plain invocation of ghci:
 {{{

 }}}

 Presumably, ghci wants to suggest the `it` variable but is getting
 confused because that variable wasn't defined in a source file.

 Note that this doesn't actually crash ghci; the prompt resumes as normal
 after the error message is printed out.
