Handling escape sequence in ansible 1.7

[aq-eng]

The following code block:

if present and block:
    # Escape seqeuences like '\n' need to be handled in Ansible 1.x                              
    if ANSIBLE_VERSION.startswith('1.'):                                                         
        block = re.sub('', block, '')                                                            
    blocklines = [marker0] + block.splitlines() + [marker1]

will crash under my test system with Ansible 1.7.

ANSIBLE_VERSION is not found and throws a NameError; my guess is that a newer version of ansible will import ANSIBE_VERSION with the wildcard imports but an older version does not. The program seems to work after removing the entire if block.
