Very interesting ... seems I missed that because in the SVN, the
_proto_tree_add_bits_ret_val function doesn't seem to support that
display style.
They call hfinfo_uint_format directly. But I think this function could
actually benefit from using fill_label_uint rather than reimplementing
the logic locally.
Cheers,
Sylvain
