The grub manual says that the return statement will use its argument as
the exit code of the function. However, all non-zero exit codes seem to
get clamped to 1:
grub> function f { return 0 ; } ; f ; echo $?
0
grub> function f { return 1 ; } ; f ; echo $?
1
grub> function f { return 2 ; } ; f ; echo $?
1
grub> function f { return 42 ; } ; f ; echo $?
1
