The `log --raw` looks useful, though I think (IIUC) I also have a problem that (obviously?) these commits are not linked behind any existing ref (except maybe the reflogs which I'm not up to speed on).

I had somehow hoped for some neat magic command or rev specifier that took the revs as alternates to the `-- <paths>` in rev-parse or some such....

It's tricky curating old mistakes ;-)

Thanks for the pointer.
