git_config_get_bool() returns 0 when it successfully finds the
variable, so the above says "If submodule.hasSuperproject is not set
at all, or if it is set to false, then..."

But given that this thing is new, I am not sure if that is a
sensible guard to use here. Shouldn't we say
- If submodule.hasSuperproject is EXPLICITLY set to false then ...
instead? I.e.
if (!git_config_get_bool("submodule.hassuperproject", &value) &&
!value) {
error(_("asked to ..."));
return 0;
}
