Incorrect View on GitHub link on rubydoc

Probably not the best place to post this, but I don't know where else.

As a concrete example, on

> http://www.rubydoc.info/github/CocoaPods/Xcodeproj/Xcodeproj%2FProject%2FObject%2FXCBuildConfiguration:build_settings

the `View on GitHub` link points to

> https://github.com/CocoaPods/Xcodeproj/blob/Xcodeproj%2FProject%2FObject%2FXCBuildConfiguration:build_settings/lib/xcodeproj/project/object/build_configuration.rb#L17

and on

> http://www.rubydoc.info/github/CocoaPods/Xcodeproj/Xcodeproj/Project/Object/XCBuildConfiguration#build_settings-instance_method

it points to

> https://github.com/CocoaPods/Xcodeproj/blob/Xcodeproj/lib/xcodeproj/project/object/build_configuration.rb#L17

instead of

> https://github.com/CocoaPods/Xcodeproj/blob/master/lib/xcodeproj/project/object/build_configuration.rb#L17
