Seems due to the below, ie, no decoration for a primary. Remains to be seen if
in other contexts (in this case the call chain is dump_template_decl ->
dump_function_decl -> dump_type -> dump_aggr_type -> dump_template_parms) we
actually do *not* want decorations, otherwise seems easy to change.

/////////////////

/* Dump the template parameters from the template info INFO under control of
   FLAGS. PRIMARY indicates whether this is a primary template decl, or
   specialization (partial or complete). For partial specializations we show
   the specialized parameter values. For a primary template we show no
   decoration.  */

static void
dump_template_parms (tree info, int primary, int flags)
{
  tree args = info ? TI_ARGS (info) : NULL_TREE;

  if (primary && flags & TFF_TEMPLATE_NAME)
    return;
