Point at span within local macros even when error happens in nested external macro
``` error[E0308]: mismatched types --> $DIR/macro-span-caller-replacement.rs:5:17 | LL | s = format!("{arg}"); | ^^^^^^^^^^^^^^^^ expected `&str`, found `String` ... LL | macro_with_format!(); | -------------------- in this macro invocation | = note: this error originates in the macro `format` which comes from the expansion of the macro `macro_with_format` (in Nightly builds, run with -Z macro-backtrace for more info) ```
