I think it's best to drop this rather large topic for now.

I started re-rolling it with improvements to address your shell escaping
comments, and ended up with a much better end-state, but it's now at
north of 30 commits locally.

So I've split it up and have some incoming patches. Not for all of it,
just starting with some of the more urgent than not fixes & more trivial
& easy to review changes, or around 1/2 of what's quoted above.

I'll then submit the rest sometime after that lands.
