How do I shorten the backtrace for a test failure in RSpec 2?

Question

When my specs hit an error, I get a message like this:

Vendor should reject duplicate names
     Failure/Error: user_with_duplicate_email.should_not be_valid

I updated it to work with with Rspec 3.2.3. In spec_helper.rb put:

RSpec.configure do |config|
  config.backtrace_exclusion_patterns = [
    /\/lib\d*\/ruby\//,
    /bin\//,
    /gems/,
    /spec\/spec_helper\.rb/,
    /lib\/rspec\/(core|expectations|matchers|mocks)/
  ]
end

This is pure gold. Thank you luacassus!
