I'm a little nervous about using this commit introducing rustyline, because the other week when I tried to go further and implement completions, I found out that the documentation is full of lies and the crate appears to be unmaintained. (I wouldn't be so bothered by one or the other of those, but the conjunction gives me pause.) But then I tried to use what appears to be the most popular linenoise wrapper, and up-arrow history didn't seem to work (even though the method names in the example code made it look like it would work), and there's an open issue from 2016 (octplane/rust-linenoise#12) that looks pretty damning. So ... let's just let this be on master and maybe swap it out later if we want completions and really can't make them work in rustyline. Consider it my karmic punishment for my delinquent co-maintainership of rusty-machine.

Hi,
The completions feature seems to be broken in version 0.2. The completion callback is only passed the most recently word, instead of the full line as in 0.1. 0.2 also adds a runtime dependency on the system's C++ standard library, which hurts portability.
