Couldn't build on nightly

[o01eg]

When I try to build latest commit 9958a54 with nightly rustc 1.30.0-dev (52c785bfc 2018-08-08) I get errors:

Looks like something changed in failure-0.1.2. Should be fixed now. I also took the opportunity to fix the deprecation warnings from AsciiExt and BufMut.
