Hello,
This patch makes the grub_checkkey() function return
a boolean value (1 = a key is available, 0 = none).
I have tested it with play.mod, and it works OK.
Note that the grub_console_checkkey() function in
term/efi/console.c already (erroneously) assumed a
boolean value, so this patch automatically fixes that.
Cheers,
