* normal/menu.c (run_menu_entry):

        * normal/command.c (grub_command_execute): If INTERACTIVE is
        false and GRUB_COMMAND_FLAG_NO_ECHO is not specified, print
        CMDLINE. Disable the pager if INTERACTIVE is true.
        All callers are changed.

        * normal/main.c (grub_normal_execute): Read command.lst and fs.lst
        before reading a config file.
        * normal/main.c (read_config_file): Even if a command is not
        found, register it if it is within an entry.

        * util/grub-emu.c: Include sys/types.h and unistd.h.
        (options): Added --hold.
        (struct arguments): Added a new member "hold".
        (parse_opt): If KEY is 'H', set ARGS->HOLD to ARG or -1 if ARG is
        missing.
        (main): Initialize ARGS.HOLD to zero. Wait until ARGS.HOLD is
        cleared by a debugger, if it is not zero.

        * include/grub/normal.h (grub_command_execute): Add an argument
        INTERACTIVE.
