     It seems to me that this really just calls for a new string
     function that allocates space without initializing it.  You could
     call it ds_append_uninitialized() and make it take the number of
     bytes to append and return a pointer to the space.  Then your
     call to data_out would look like this:
             data_out (ds_append_uninitialized (&s, v->print.w),
                       &v->print, case_data (v, v->fv));
     Of course, you could break the call to ds_append_uninitialized()
     into a separate statement if that looks too obscure.

You're right.  I'll do something like that.
