* normal/misc.c: New file.

        * DISTLIST: Added normal/misc.c.

        * partmap/amiga.c (amiga_partition_map_iterate): Add an argument
        DISK to HOOK. Call HOOK with DISK.
        * partmap/apple.c (apple_partition_map_iterate): Likewise.
        * partmap/pc.c (pc_partition_map_iterate): Likewise.
        * partmap/sun.c (sun_partition_map_iterate): Likewise.

        * normal/menu_entry.c (struct screen): Added a new member
        "completion_shown".
        (completion_buffer): New global variable.
        (make_screen): Set SCREEN->COMPLETION_SHOWN to zero.
        (store_completion): New function.
        (complete): Likewise.
        (clear_completions): Likewise.
        (grub_menu_entry_run): If SCREEN->COMPLETION_SHOWN is non-zero,
        call clear_completions and reset SCREEN->COMPLETION_SHOWN. If C is
        a tab, call complete.

        * normal/completion.c (disk_dev): Removed.
        (print_simple_completion): Likewise.
        (print_partition_completion): Likewise.
        (print_func): New global variable.
        (add_completion): Do not take the arguments WHAT or PRINT any
        longer. Added a new argument TYPE. Instead of printing directly,
        call PRINT_FUNC if not NULL.
        All callers changed.
        (complete_device): Use a local variable DEV instead of
        DISK_DEV. Do not move CURRENT_WORD to the end of a device name.
        (grub_normal_do_completion): Take a new argument HOOK. Do not
        initialize DISK_DEV. Initialize PRINT_FUNC to HOOK. If RET is an
        empty string, return NULL instead.
        All callers changed.

        * normal/cmdline.c (print_completion): New function.

        * kern/partition.c (grub_partition_iterate): Add an argument DISK
        to HOOK.
        All callers changed.

        * kern/disk.c (grub_print_partinfo): Removed.

        * include/grub/partition.h (struct grub_partition_map): Add a new
        argument DISK into HOOK of ITERATE.
        (grub_partition_iterate): Add a new argument DISK to HOOK.

        * include/grub/normal.h (enum grub_completion_type): New enum.
        (grub_completion_type_t): New type.
        (GRUB_COMPLETION_TYPE_COMMAND): New constant.
        (GRUB_COMPLETION_TYPE_DEVICE): Likewise.
        (GRUB_COMPLETION_TYPE_PARTITION): Likewise.
        (GRUB_COMPLETION_TYPE_FILE): Likewise.
        (grub_normal_do_completion): Added a new argument HOOK.
        (grub_normal_print_device_info): New prototype.

        * include/grub/disk.h (grub_print_partinfo): Removed.

        * conf/i386-pc.rmk (grub_emu_SOURCES): Added normal/misc.c.
        (normal_mod_SOURCES): Likewise.
        * conf/powerpc-ieee1275.rmk (grub_emu_SOURCES): Likewise.
        (normal_mod_SOURCES): Likewise.

        * commands/ls.c (grub_ls_list_disks): Use
        grub_normal_print_device_info instead of grub_print_partinfo. Free
        PNAME.
        (grub_ls_list_files): Use grub_normal_print_device_info instead of
        duplicating the code.
