Title: Any interest in something like this - display the source location for a duplicate shared example group

I couldn't get the specs to run on ruby 1.9 because of the ruby-debug / debugger issue so this is more of a speculative pull request.

If it looks likely people will find something like this useful I can sort the specs out this weekend.
