11490: Correctly fix formatting doc tests with generics r=Veykril a=KarlWithK Before the doc_test would be outputted like this: ```zsh "Foo<T, U>::t" ``` However, this would cause problems with shell redirection. I've changed it so when generics are involved we simply wrap the expression under quotes as so: ```zsh "\"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 ``` Closes https://github.com/rust-analyzer/rust-analyzer/issues/11489 Co-authored-by: KarlWithK <[email protected]> Co-authored-by: SeniorMars <[email protected]>
