'echo -e' is inherently non-portable; you should get in the habit of
using printf(1) instead.

Thanks for the report. However, I don't think it is a bug. The empty
line, when forced to take on a numeric value, is equivalent to 0. And
since you specified unique entries only, sort only printed the empty
line (the first of the two matching lines that it encountered).
