Rcov fails after upgrading from 2.6.0 to 2.8.0

[Confusion]

I just upgraded from 2.6.0 to 2.8.0 and after that rcov fails to run. It produces no output at all and any check on coverage subsequently fails. Some quick googling yielded http://blog.thefrontiergroup.com.au/2011/05/rspec-2-6-0-and-rcov/ and indeed, adding

require 'rspec/autorun'

to the spec_helper.rb solved the issue. I guess that file is still intended to be required automatically?

We can't require it automatically because doing so means that just loading rspec into the environment means the specs will run. We have yet to come up with a reliable automatic way to do it, and until we do it's going to remain a burden on the user to require 'rspec/autorun'.

I'll leave this open as a reminder to improve the documentation around this.
