Subject: [PATCH] Deal with shellcheck warnings in 1993/plummer

This was only in try.sh: SLEEP is not needed which is why the error was
not detected. SLEEP is only relevant to the alt code. But the try.alt.sh
was updated to make it shorter for assigning the default:

    [[ -z "$SLEEP" ]] && SLEEP=1000

1000 is the default in the Makefile.
