expected result:
compile gitlab-shell seccess

Start with bin/install, install.sh, and the Makefile target that runs go install ./cmd/...; review how the build fetches github.com/mattn/go-shellwords. Reproduce the Docker build and determine whether the dependency-fetch failure is addressed; done means the gitlab-shell executables compile successfully.
