@mumme74, thank you for the pull request. I spent some time to review it, and I acknowledged some good ideas in it.

I also did some research about how other PEG parsers handle tracking, and found the following one gives an interesting idea as well. https://docs.rs/peg/0.6.1/peg/#tracing

I'll ponder over how the tracing feature can be improved. Thank you!

I have changed the trace feature which can now show whether a rule matched or not. https://github.com/yhirose/cpp-peglib/commit/fe2d67fc88e2ca69bfdd6630532efc8909e76e09
