strdup return of cmdparams_get_str()

/*
 *  smpl_02.c						$DRMS/proj/cookbook/
 *
 *  Annother simple module that does nothing but echo back the values of
 *    arguments. It illustrates the use of command line parsing and the
 *    variety of argument types; also introduces time string functions
 *
 *  Usage:
 *    smpl_02 [-avVH]
 *
 *  Bugs:
 *    The module is of no particular use, and exists merely for heuristic
 *      and testing purposes.
 *
 *  Revision history is at end of file.
