Description

I haven't figured out exactly what's going on here yet, but to repro:

mkdir /tmp/rustdoc-dirty && cd /tmp/rustdoc-dirty && cargo init echo 'futures-preview = { version = "=0.3.0-alpha.16", features = ["io-compat"] }' >> Cargo.toml cargo doc cargo doc

(tested on rustc 1.36.0-nightly (a784a8022 2019-05-09))

The second cargo doc should do no work and immediately exit, however it instead proceeds to document tokio-io and everything after it. This only happens when the io-compat feature is enabled, but does not happen when depending directly on tokio-io.
