Maybe deprecate it? I suppose the implementation of the aliasing is easy enough that we can carry `--submodule` around forever, though. > diff --git a/diff.c b/diff.c > index 145cfbae592..d3d5a989bd1 100644 > --- a/diff.c > +++ b/diff.c > @@ -5023,6 +5023,8 @@ int diff_opt_parse(struct diff_options *options, > handle_ignore_submodules_arg(options, arg); > } else if (skip_to_optional_arg_default(arg, "--submodule", &arg, "log")) > return parse_submodule_opt(options, arg); > + else if (skip_to_optional_arg_default(arg, "--recurse-submodules", &arg, "log")) > + return parse_submodule_opt(options, arg); 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?
