Fix ICE rust-lang#91268 by checking that the snippet ends with a `)` Fix rust-lang#91268 Previously it was assumed that the last character of `snippet` will be a `)`, so using `snippet.len() - 1` as an index should be safe. However as we see in the test, it is possible to enter that branch without a closing `)`, and it will trigger the panic if the last character happens to be multibyte. The fix is to ensure that the snippet ends with `)`, and skip the suggestion otherwise.
