The completion code is heavily modified.
* stage2/char_io.c [!STAGE1_5] (get_cmdline): In the completion
code, use COMPLETION_BUFFER to get the completion instead of
writing to BUF directly.
Save the position of a possible equal character after a command
in EQUAL_POS and replace the equal character with a space
temporarily for the code simplicity.
At first, just get completions, and, if there is more than one
completions, then print the list of the completions.
* stage2/disk_io.c [!STAGE1_5] (do_completion): New variable.
[!STAGE1_5] (unique): Moved the definition near the beginning.
[!STAGE1_5] (unique_string): Likewise. And changed the type to
char *.
(check_BSD_parts) [!STAGE1_5]: If DO_COMPLETION is non-zero, do
not print anything.
(real_open_partition) [!STAGE1_5]: Likewise.
[!STAGE1_5] (print_fsys_type): Likewise.
[!STAGE1_5] (print_a_completion): The argument FILENAME is
renamed to NAME.
If DO_COMPLETION is non-zero, get the unique part from NAME and
set UNIQUE_STRING to it.
If DO_COMPLETION is zero, just print NAME.
Do not call printf unconditionally.
[!STAGE1_5] (print_completions): Accept two arguements
IS_FILENAME and IS_COMPLETION instead of FILENAME.
Set UNIQUE_STRING to UNIQUE_BUF.
Set DO_COMPLETION to IS_COMPLETION and set it to zero before
returning.
If IS_FILENAME is zero, then complete builtin commands and
return UNIQUE - 1.
Use BUF instead of FILENAME.
If IS_COMPLETION is non-zero, do not print anything.
Copy UNIQUE_STRING to PTR only if IS_COMPLETION and
*UNIQUE_STRING are non-zero.
* stage2/shared.h (COMPLETION_BUF): New macro.
(COMPLETION_BUFLEN): Likewise.
(UNIQUE_BUF): Likewise.
(UNIQUE_BUFLEN): Likewise.
(MENU_BUF): Set to UNIQUE_BUF + UNIQUE_BUFLEN.
(MENU_BUFLEN): Set to 0x8000 + PASSWORD_BUF - UNIQUE_BUF.
(print_completions): Adjusted to the definition.

* acinclude.m4 (grub_ASM_PREFIX_REQUIREMENT): Do not call
