Subject: [PATCH] Redirect stderr to /dev/null in 1991/dds/README.md

This is to prevent annoying warnings about gets() - as changing this one
to use fgets() would be very complicated. This can be done for other
entries that use gets() that are either complicated to change or it's
decided to not change them. It won't prevent linker warnings (like with
gcc) but it'll prevent runtime warnings that often get interspersed with
the output of the program sometimes in confusing ways.
