Look like the same problem in #58

I guess the non block mode use pexpect and block mode use subprocess directly...

And when use subprocess with shell=True, the list[1:] will be ignored....

The packages version:

delegator.py==0.1.1
  - pexpect [required: >=4.1.0, installed: 4.6.0]
    - ptyprocess [required: >=0.5, installed: 0.6.0]
