Should investigate why this was done, since it appears to be deliberate. Thanks for the work, Xin!

I debugged step by step, and finally find the reason why robots.txt is downloaded everytime. Before download robots.txt, opt.timestamping is set to false, so no initial HEAD is sent.

Attached patch could fix this issue. But I still don't know why original author did this.

Sorry, the specific behavior that's undesirable is that "robots.txt.2", etc, is saved, rather than timestamping on "robots.txt" and saving to that.

From the output, it doesn't appear that the initial HEAD is sent, either (should verify that with -d).
