Include the spec location in warnings if we can't generate a call site.
Fix RSpec.warn_with to inherit from RSpec::Support
Remove source_location from example, favouring #location
Make clone all script pull the correct branch of rspec support
Cleanup out of spec warning handling
Append periods to warning messages if not provided
Period check that works on 1.8.7
Make spec locations be shown on their own option
Prefer end with over chars.to_a.last
More cleanup of warnings using specs as call sites
