Ok, the problem is not that filtered prints were not used, but that
there is code in fputs_maybe_filtered to bypass the filtered print, if
this condition is true:

  /* Don't do any filtering if it is disabled.  */
  if ((stream != gdb_stdout) || !pagination_enabled
      || (lines_per_page == UINT_MAX && chars_per_line == UINT_MAX))
    {
      fputs_unfiltered (linebuffer, stream);
      return;
    }

In this case, stream is different from gdb_stdout.

Can you try this patch?
