Leading `\` in TEMPLATE in fastentrypoints.py

[coldfix]

Hey, I just noticed in your fastentrypoints.py that #872 introduced a potential problem with the entrypoint generation:

https://github.com/nvbn/thefuck/blob/master/fastentrypoints.py#L40

It should read:

- TEMPLATE = r'''\
+ TEMPLATE = r'''

and then use .lstrip() or [1:] to correct for the initial newline since the \ escape for line endings doesn't work within raw strings.

Best, Thomas
