We determined via chat that calling gitmodules_config
is not harmful w.r.t. correctness, but might require some
improvements in the future for performance.
(i.e. we may want to add in a later series a
    if (already called gitmodules_config)
      set flag "already called gitmodules_config";
      return;
into gitmodules_config)

Here we need a strbuf_release(&buf) to avoid a memory leak?
