Looks good to me, I would only add "with the same filename" after
"--etag-compare".

I would make that "*possibly* with the same filename".  That should
be obvious from the necessary processing sequence, yet I satisfied
myself by experiment that it works.

Perhaps I'm unduly cautious about using the same file for both input
and output for any process.
