cargo plugin sub commands no longer work in nightly version

[sagiegurari]

All subcommands that come from external crates stopped working with the latest nightly cargo.

rustc --version
rustc 1.26.0-nightly (a04b88d19 2018-03-19)
rustup --version
rustup 1.11.0 (e751ff9f8 2018-02-13)
cargo --version
cargo 1.26.0-nightly (d6c3983fe 2018-03-16)

Installing /home/travis/.cargo/bin/cargo-make
The command "cargo install --debug cargo-make" exited with 0.

Yep, that's a known issue that I've broken all subcommands on nightly :-(

The issue is already fixed in Cargo, the PR with Cargo update to rust-lang/rust is https://github.com/rust-lang/rust/pull/49182

Looks like https://github.com/rust-lang/rust/pull/49182 merged a couple of days ago, although I'm not sure which nightly it'll ride -- with nightly-2018-03-21 from rustup I'm seeing cargo 1.26.0-nightly (d6c3983fe 2018-03-16).

@matklad when can we expect a fix for this? I tried the latest nightly and its still failing.

@sagiegurari It looks like a new nightly has been pushed with the update to cargo.

Thanks @ehuss you are right. Works great now.
