Code review comment for lp:~salgado/linaro-image-tools/standardise-indentation

Thanks for the review, Alexander.

I ran it on a headless tarball and it generated an image which was
exactly the same size as that generated by trunk's linaro-media-create.

I wasn't able to boot it using qemu but that's likely to not be related
to my changes as I can't boot the img generated with trunk's version
either.
