Rewriting the GNU Coreutils in Rust

Being usable as a drop-in replacement of coreutils is a stated critical requirement of uutils, but I sure hope that uutils will eventually gain user-facing well-thoutght-out features as well.

In my youthful days I'd read all the coreutils changelogs and get excited about new features. Yesterday's bells are today's must-have. A lot of the entries in http://www.gnu.org/software/coreutils/rejected_requests.html look really reasonable and useful to me.
