Personally I don't like approach with string split because it is potentially less efficient due to memory allocations in case of multiple newlines that can be avoided. BUT I would like to move the needle and fix this real bug in clang ASAP. So I'm ready to rewrite it to something that (1) works and (2) moves review forward. So thank you for review and please take another look.
