Huh? That seems very surprising given that we use this pattern in plenty of
other places:
https://github.com/llvm/llvm-project/blob/main/clang/include/clang/Basic/DiagnosticSemaKinds.td#L483
https://github.com/llvm/llvm-project/blob/main/clang/include/clang/Basic/DiagnosticSemaKinds.td#L685
https://github.com/llvm/llvm-project/blob/main/clang/include/clang/Basic/DiagnosticSemaKinds.td#L1439
Can you post the output you're getting when you try my workaround? (I don't
know if your original attempt will work because of the lack of whitespace
before the `%select` in `object%select`.)
