A couple of comments - (and I don't know what infra's take on
pre-commit hooks is, they may be verboten)

Before this work started I'd like to see a pre-commit hook that
rejects commits with tabs, so that we stop the problem. (I also want
to see testing for line endings) Line endings and spaces are easy
places to start from a coding convention requirement phase, and we can
continue to build that up.

Aside from that, I'd love to see this done.
