I've been hacking on that some more (I'll post it as soon as I
have all new tests up and running) and think we might be able to
handle that even easier. Please see below:

You'll have to do this unconditionally, as this option tells the
diff machinery to ignore any submodule configurations, which is
what we want in either case. But ...

... maybe the best way is to leave index_differs_from() unchanged
and call that function with the correct diff_flags instead:
+ int diff_flags = DIFF_OPT_OVERRIDE_SUBMODULE_CONFIG;
+ if (ignore_submodule_arg &&
+ !strcmp(ignore_submodule_arg, "all"))
+ diff_flags |= DIFF_OPT_IGNORE_SUBMODULES;
+ commitable = index_differs_from(parent, diff_flags);
Not thoroughly tested yet, but that'd also prevent any fallout for
the two callsites of index_differs_from() in sequencer.c.
