Complete changed the way format strings are handled. They are now compiled first, which is far more efficient than what was being done before. Also, there is now a global ledger::commodity_t::commodities map, which saves me from having to pass the current journal around to a zillion different functions, for the sole purpose of making sure that all commodity symbols that are parsed refer to the same commodity object.
