Also surround it in square brackets rather than parentheses. This matches the format used by Clang and GCC, and means diagnostics will still match the `file:line:col: error: ` pattern used by some IDE tools. Before: ```console fail_builtins.carbon:11:11: error(AliasRequiresNameRef): alias initializer must be a name reference ``` After: ```console fail_builtins.carbon:11:11: error: alias initializer must be a name reference [AliasRequiresNameRef] ``` Also tighten up test regex to only match on `STDERR` lines that list a file name.
