Before the doc_test would be outputted like this: "Foo<T, U>::t" However, this would cause shells with shell redirection. I've changed it so when generics are involved we simply wrap the expression under escape chanters as so: "\"Foo<T, U>::t\"" Note: At the cost of adding this, I had to allocate a new string via format!{}. However, I argue this is alright as this for just for outputting the name of the doc test. The following tests have been changed: runnables::tests::doc_test_type_params runnables::tests::test_doc_runnables_impl_mod runnables::tests::test_runnables_doc_test_in_impl
