Append a null byte to all keys

V8.1 and above

If a database was created with makemap 's -N switch (-N) to include the terminating zero byte with each key, this -N switch should be specified with the corresponding K configuration command to force all lookups to also include a zero byte. Note that -N is not needed for the nis type and, if included, is ignored. See also -O in -O.
