If one is using a nightly Rust compiler they should compile clap
with the `nightly` feature.
```toml
[dependencies]
clap = { version = "2.27", features = ["nightly"] }
```
This isn't required for compilation to succeed, only to take
advantage of any nightly features used by clap.
If one is compiling with `#[deny(warnings)]` this commit will cause
compilation to fail if one *does not* compile with the `nightly`
since `std::ascii::AsciiExt` is no longer required in in multiple
files as of the latest Rust nightly (Nov 6th, 2017).
