Criterion 0.4 --bench --compare error

[tower120]

Whenever I run --bench -- --compare --baselines, I get this error:

 C:\github\any_vec> cargo bench --bench=iter -- --compare --baselines criterion_0_4,criterion_0_4
    Finished bench [optimized] target(s) in 0.26s
     Running benches\iter.rs (target\release\deps\iter-ad9f3b5828e8624c.exe)

I assume this is something clap -related.

Hello, and thanks for the bug report.

I'm afraid I don't know anything about the --compare option. @lemmih, does this make sense to you?
