Only if there is any chance of return, and we can handle it.

"exit" in open firmware based systems would probably mean returning
control to open firmware.

By the way, it would be nice to have "exit" in both grub for PC and
grub-emu, and not only in the rescue mode.  "exit" on PC means returning
control to BIOS so it can try another boot device.  "exit" in grub-emu
means exit, of course.  I have to use "reboot" now (which should not
exit, but rather restart grub-emu, if it belongs to grub-emu at all) or
"rescue" followed by "exit".
