Changed ft_dump, ft_eval, ft_test1, mi_test1, myisampack, gen_lex_hash,
mysqlmanager from using GNU getopt to use my_getopt. Changed some files that just included old getopt.h to include my_getopt.h now. Fixed a bug in my_print_help() in my_getopt.c. Made better documentation for option -G in mysql client. client/mysql.cc: Documented --named-commands better. myisam/ft_dump.c: Changed getopt to my_getopt. myisam/ft_eval.c: Changed getopt to my_getopt. myisam/ft_test1.c: Changed getopt to my_getopt. myisam/mi_check.c: getopt.h -> my_getopt.h myisam/mi_test1.c: Changed getopt to my_getopt. myisam/myisampack.c: Changed getopt to my_getopt. mysys/my_getopt.c: Fixed a bug when printing help for option that didn't have a description. sql/gen_lex_hash.cc: Changed getopt to my_getopt. tools/mysqlmanager.c: Changed getopt to my_getopt. vio/test-ssl.c: getopt.h -> my_getopt.h vio/test-sslclient.c: getopt.h -> my_getopt.h vio/test-sslserver.c: getopt.h -> my_getopt.h vio/viotest-ssl.c: getopt.h -> my_getopt.h BitKeeper/etc/logging_ok: Logging to logging@openlogging.org accepted
