temporary_cstring_as_ptr lint doesn't correctly trigger

[crlf0710]

While let _f = CString::new("foo").unwrap().as_ptr(); correctly triggers temporary_cstring_as_ptr lint, let _f = CString::new("foo").expect("dummy").as_ptr() doesn't. What's the difference between unwrap and expect?

I'm using rustc stable 1.36.

Yes this should trigger for both unwrap and expect.
