delegator.chain() adds an extra newline into pipes

[LucidOne]

Expected results

$ seq 4 | awk '{ print $0 " test"; }'
1 test
2 test
3 test
4 test

Actual results

$ python test.py 
1 test
2 test
3 test
4 test
 test

test.py

#!/usr/bin/env python
import delegator
c = delegator.chain("seq 4 | awk '{ print $0 \" test\"; }'")
print(c.out)

If I substitute delegator.run() for delegator.chain() it works correctly. Tested with v0.1.0, seems to happen in both python2 and 3
