bug

What is the current behavior?

package.json scripts part:

  "scripts": {
    "production": "webpack -p"
  },

yarn command:

yarn run production

output:

yarn run v0.18.1
error No command specified.
info Commands available from binary scripts: webpack, webpack-dev-server
info Project commands
   - production
question Which command would you like to run?:

If the current behavior is a bug, please provide the steps to reproduce.

Same as above.

N.B.: The problem seems to exist for only if the script is named production. For example, if we change the name:

  "scripts": {
    "product": "webpack -p"
  },

yarn run product works just fine.

What is the expected behavior?

run the script with no error...
