Mysterious failing build on nightly (missing feature 'osstring_simple_functions')

[ketsuban]

My build is failing on nightly, complaining about a missing feature annotation in clap. The weird thing is that the previous commit, using the nightly from a couple days before with the same version of clap, worked fine and complained only about something in my code which previously was allowed and is being phased out.

I can't rightly tell if this bug is yours or a regression of some sort in the compiler, but I thought it prudent to tell you and let you decide what to do because you're my direct upstream.

rust-lang/rust#29453 recently added #433 should fix this.

v2.1.2 on crates.io should fix this for you.
