> I just tried "clang-format -i" on the file with your patch, and it seems to compute the correct indentation here.  This with a source tree and clang-format binary from feb 28 because that's what I had handy... but I don't think anything relevant has changed here?
Running clang-format on the whole file really seems to produce correct formatting... But it is a lot of unrelated changes. Running clang-format only on the `mangleNestedName` function (`--lines=1185:1287` without my changes, `--lines=1242:1349` with my changes) produces bad formatting.

-      QualType T = Base.getType();
+      std::stack<char> EntryTypeStack;
+      SmallVector<std::function<void()>, 2> EntryManglers;

`std::stack` can be parameterized with container type (`std::stack<char, SmallVector<char, 2>>`). Or it should not be used for some other reason?
