I think some of these will want to remain in cat-file.c. For instance, split_on_whitespace is not something that ref-filter.c itself would care about. I'd expect in the endgame for cat-file to keep its own split_on_whitespace flag, and to set it based on the presence of the %(rest) flag, which it can check by seeing if the "rest" atom is in the "used_atom" list after parsing the format. -Peff
