Hi,

Find attached the patch and ChangeLog for normal_menu.c

Suggestions? What to change?

Notice that I used grub_printf to print the spaces/new lines of
formatting.

And print_message_indented receive a "long" string and prints it
splitting by the spaces and indented 6 spaces.

(15 and 6 in that method could be macrofied or const int spaces = 6,
would be in normal.h ?)
