* stage2/char_io.c [!STAGE1_5] (auto_fill): New variable.
[!STAGE1_5] (get_cmdline): Save AUTO_FILL in SAVED_AUTO_FILL in
the beginning and restore AUTO_FILL before return.
Set AUTO_FILL to one and zero before and after calling
print_completions, respectively.
(grub_putchar) [!STAGE1_5]: Use a static variable COL to track
the position of the cursor. If C is a carriage return, clear
COL. If C is a backspace and COL is positive, decrease COL. If C
is a printable character, increase COL. In this case, if
AUTO_FILL is non-zero and COL is greater than or equal to 79,
put a newline automatically.
* stage2/shared.h (auto_fill): Declared.
* stage2/stage2.c (run_menu): In the menu interface, disable the
auto fill mode (i.e. set AUTO_FILL to zero), and enable it again
when booting an entry.
(cmain): Initialize AUTO_FILL (i.e. set it to one) in the
beginning of the loop.
