I meant that if you take the test and run it on unpatched master (simulating 
hypothetical test failure in the future) the message it produces starts by 
stating that the expected string (part of the testcase) is "unstable" which 
seems a bit unclear/confusing to me.

  
/Users/jankorous/src/llvm-monorepo/llvm-project/clang/unittests/Format/FormatTest.cpp:74:
 Failure
        Expected: Expected.str()
        Which is: "namespace bar {\nauto foo{[]() -> foo<false> { ; }};\n} // 
namespace bar"
  To be equal to: format(Expected, Style)
        Which is: "namespace bar {\nauto foo{[]() -> foo<false>{;\n}\n}\n;\n} 
// namespace bar"
  With diff:
  @@ -1,3 +1,6 @@
   namespace bar {
  -auto foo{[]() -> foo<false> { ; }};
  +auto foo{[]() -> foo<false>{;
  +}
  +}
  +;
   } // namespace bar

Whereas the full original reproducer (with the "//// broken:" comment included) 
also starts with the same message but the diff implies that the implementation 
is wrong by duplicating the "//// namespace bar" comment.

Anyway. LGTM.
