Sorry that progress has been quite slow this week.
My work-in-progess lays out the syntax of the command,
the initial parsing and object lookup.
I still need to break out the tree and path dereferencing logic.
I haven't started on printing yet but I presume it should be easy.

Thanks for this, it should have gone in much earlier.

Testing against my favourite, the ASF repo, as I write this.

That's odd, I was able to import up to r354 before receiving:
fatal: missing newline after cat-blob response

So there's some regressions to chase down since the last roll-up.

That's all I've got for now.
