The indentation style being used in Zamboni violates pep8, see 

E121 continuation line indentation is not a multiple of four
E128 continuation line under-indented for visual indent

I agree our indentation style should be consistent, so I'll modify my code to follow a hanging indent style but it seems that we have a lot of pep8 violations so running an automated pep8 validator seems useless until we can clean up a lot of the violations?
