lrzip goes in infinite loop when given -w -15 command line arg

The following is a command that I have lrzip on a 900MB file. I tried it with -vvv and it was trying to compress 0 bytes many hundreds of times, and didn't appear to stop compressing.

decagon@server:/tmp/test$ lrzip -w -15 -vl test.out

Yeah that's interesting, it shouldn't allow negative numbers.
