Comment (by daira):

 We discussed this during Nuts and Bolts, and I was persuaded that we
 should Zooko's comment:27 algorithm despite the difference from `/bin/cp`
 (as tested on OS X). The clinching arguments were:
 * `/bin/cp` doesn't behave consistently across platforms anyway. Its
 different treatment of a trailing slash on some platforms is confusing and
 I don't think we should emulate that.
 * Zooko's proposed algorithm has a symmetry between the target-present and
 target-not-present cases that I hadn't previously noticed, and that may
 help to prevent race conditions.
