... and mention `--submodule` here as a historical alias? Maybe
deprecate it? I suppose the implementation of the aliasing is easy
enough that we can carry `--submodule` around forever, though.

How about (whitespace-damaged)
} else if (skip_to_optional_arg_default(arg, "--submodule", &arg, "log") ||
skip_to_optional_arg_default(arg, "--recurse-submodules",
&arg, "log"))
return parse_submodule_opt(options, arg);
to make this future-proof? Sure, they're close enough that one should
notice the two instances, and any future work work would supposedly
happen in `parse_submodule_opt()` or anywhere else but here, but still.
Just a few thoughts.
