I'm not 100% sure whether we would just try to use the Preprocessor for this, or whether we'd want to only allow a small subset of actual macros, but the general idea would be the same: The UnwrappedLineParser would parse the macro at the expansion location A(X) into an unwrapped line, and then parse the expansion into a child line, with the tokens tha tare not in the argument of the call being marked as fixed (parent child might also be better inverted).

I believe this will be needed for various reasons. The plan is to make this similar to how we format #ifdef trees, for which clang-format already has full support.

Some initial design work has been done, and Krasimir said that he's interested. No timeline though :(
