Regression, `cargo r` doesn't work anymore (but `cargo run` does)

[Boscop]

I just updated my nightly to

rustc 1.32.0-nightly (b3af09205 2018-12-04)

And cloned indicatif, trying to run the examples fails with

D:\3rdparty\indicatif> cargo r --example single
error: a bin target must be available for cargo run

when I write cargo r --example single it works, but it used to work before also with cargo r.
Why not anymore?

Similarly, cargo b --examples just returns immediately with Finished dev [unoptimized + debuginfo] target(s) in 2.12s without having built the examples. When I then run cargo build --examples it actually builds them:

D:\3rdparty\indicatif> cargo build --examples

   = note: #[warn(deprecated)] on by default

    Finished dev [unoptimized + debuginfo] target(s) in 4.24s

Also, when I try to use -- to pass args to my program, it doesn't work anymore (it definitely worked yesterday before updating my nightly):

> cargo r --release -- foo.txt bar.txt
    Finished dev [unoptimized + debuginfo] target(s) in 0.40s
     Running `D:\myproject\target\debug\pipeline.exe`
error: The following required arguments were not provided:
    <path_en>
    <path_de>

USAGE:
    pipeline.exe [FLAGS] <path_en> <path_de>

For more information try --help
error: process didn't exit successfully: `D:\myproject\target\debug\pipeline.exe` (exit code: 1)

Btw, I'm using quicli which uses structopt/clap.

Notice that even though I'm passing --release, cargo is running the debug version of my exe! (But again, if I use run instead of r, it behaves correctly!)
Something is seriously borked here..

This regression was due to my commits (#6259). Thank you for fixing @ehuss !
