Originally filed at crbug.com/1184570.
When the name of a namespace is a macro that takes arguments,

- It fixed the indentation.
- It tried to fix namespace end comment by making the name empty, because we

don't know the macro expansion. It seems like `FormatToken::MacroCtx` is always
None. Its assignment only happens in `MacroExpander` which is never used.
