Subject: clarify lack of checking speed lower bound
X-Git-Url: http://challenge-bot.com/repos/?p=challenge-bot;a=commitdiff_plain;h=d77c514c0f5c727a0ba0942fedc313c0daaf77f2

clarify lack of checking speed lower bound

speed is guaranteed to be non-negative by this point in the code, so
there's no need to test if it's too negative.
