In execute.c, coverity dinged this potential NULL-deref:
163 return grub_strtoul (grub_env_get ("?"), NULL, 10);
If grub_env_get ("?") can indeed return NULL,
you'll want to accommodate the possibility.
It would be nice to do that even if somehow
a NULL return is not possible, just to avoid the FP.
