##### Issue Type:
Bugfix Pull Request
##### Ansible Version:
ansible 1.4.3
##### Environment:
N/A
##### Summary:
We are using a wrapper python script to run ansible-playbook. We use subprocess to execute and print the stdout as and when its written. Problem is when we use pause it doesn't display the prompt string as raw_input does not flush stdout before reading from stdin.
It looks like a dirty fix to add "\n" to the prompt string but i don't see any other way to over come this. If anyone else have a better fix please do propose/suggest.
##### Steps To Reproduce:
```yaml
#File: test_play.yml
- name: Test
hosts: $nodes
gather_facts: false
tasks:
- name: Waiting for User
local_action: pause prompt="Do you want to continue (yes/no)? "
```
```python
#!/usr/bin/env python
#File: test.py
import shlex, subprocess
def run_process(process):
process = process.encode("utf-8")
command = shlex.split(process)
p = subprocess.Popen(command, stdout=subprocess.PIPE, stderr=subprocess.STDOUT)
for line in iter(p.stdout.readline, b''):
print line,
cmd = "/usr/bin/python -u /usr/bin/ansible-playbook -i hosts.txt test_play.yml -e 'nodes=local'"
run_process(cmd)
```
```
shell $ python test.py
```
##### Expected Results:
```
PLAY [Test] *******************************************************************
TASK: [Waiting for User] ******************************************************
[localhost]
Do you want to continue (yes/no)? :
```
##### Actual Results:
```
PLAY [Test] *******************************************************************
TASK: [Waiting for User] ******************************************************
[localhost]
```
