Sorry. Thanks for the correction. I've been looking for those words
for some time. Thought I'd checked that file, as a matter of fact,
yet as you can see I remained confused. Maybe it'll stick this time.

Does "diff -rM URL1 URL2" mean "diff URL1 against URL2 in some way"?
Or "diff URL1 against some -rM ancestor of itself, then do that again
for URL2"?
If the former, then isn't "M" being used twice, once to select "the
pegged node-rev", and again to specify "the start rev"? That would
be what I meant by "muddled."

Actually, I said "gosh, that's a great example and makes it very clear."
