Empty line after before_script

Seems to be inconsistent with YML format. Is that bein used? is script supposed to be inside before_script? not clear.

I'm not sure if the YAML doesn't allow it but Travis YAML file validation script displays a warning once the before_script node is empty.

Warnings for .travis.yml:
[x] value for before_script section is empty, dropping

I think the empty line is there to show that script: node isn't inside before_script.

Once before_script seems not being used I think we can remove it. I will do it and send a pull to my repo and see if everything is still working.

I think it's there for no reason. YAML follows indentation. Let me know if that works.
