You're right; this patch only works for a single fallback entry, which is better than nothing.

If you think nothing is better, then eliminating the first if-statement leaves a patch that at least fixes the NUM case.

A working NUM case makes it possible to work around the inability to save fallback. The example in "4.3.2 Booting fallback systems" can be rewritten as

title A
savedefault 1

title B
savedefault 2

which is functionally equivalent.

I'll think about how to handle a fallback list, but it seems hard.

$fallback can be list of entries, while $saved_entry is expected to be
single menu entry. GRUB legacy documentation is unclear what "next
fallback" means here and what happens if you do several consecutive
"savedefault fallback" invocations, but it still explicitly says "next
fallback entry", not "list of fallback entries".
