[Bug-readline] Improving support for rl_set_screen_size's restrictions

GDB had a bug, which was fixed recently, where it would pass large values to rl_set_screen_size (which multiplies the arguments it’s given) and lead to undefined behavior. On the gdb-patches mailing list, it was mentioned that there is no documented maximum size for the rows or columns parameters. Is this something that Readline would be willing to improve, either through better documentation or better handling? I can  send in a patch for this if this is something that would be appreciated.
