nx_ini_writer.nx

ini_writer.nx -- serialise INI-style config. Companion to ini.nx (reader). Stream builder emits files that ini.nx round-trips exactly: [section] key = value ; comment We always use \" = \" (space-equals-space) separator and LF line endings. This matches typical Unix convention; Windows tools tolerate LF. Invariants: IW1 Keys and values emitted verbatim -- no escaping. INI has no standard escape form; values with newlines are inherently unsafe in INI, caller pre-sanitises. IW2 ini_writer_section groups the next keys under that name until another section is opened. IW3 Round-trip: ini.nx parsing our output yields the original (section, key, value) tuples.
