 * ypall.c

 * `ypcat` using ypall().
 * ypall has advantages because it uses a single RPC request/response
 * over TCP, rather than 'n' RPC request/responses over UDP.
 *   (see 'ypcat.c')
 *
 * This way is cleaner, better, but also buggy.
 * Most bugs are gone, but you still get the last entry from the map twice.
