[Merge] lp:~stgraber/upstart/upstart-initctl2dot-python3 into lp:upstart

[Stéphane Graber]

Thanks for the comments. I removed those last few globals and fixed a mistake I did in the output file so that it's now valid. While I was at it, I also tweaked the code a bit so that the output file's indentation is correct.
