* dumpv4.c:
	  The V4 master key & schedule was never initialized,
	so the dump created by dump_v4db was garbage.   Read the V4
	master key from /.k or prompt for the V4 master key password.
	  If there is no V4-salt key in the database, but there is a DES
	key, include it in the V4 dump, in case it is merely a random
	service key for which there is no associated password.
	  Skip over K/M in the V5 database (use the entered V4 master key).
	  Both krbtgt and afs keys often have domain-qualifed instances.
