use backticks instead of single quotes when reporting "use of unstable library feature" This is consistent with all other diagnostics I could find containing features and enables the use of `DiagSymbolList` for generalizing diagnostics for unstable library features to multiple features. 2024-11-02 16:10:24 -07:00			use std::marker::CoercePointee; //~ ERROR use of unstable library feature `derive_coerce_pointee`
