I would watch out with diff - there are examples in the book and code that
depends on the current diff behavior (which is somewhat confusing when
used with --old/--new and peg revisions *and* the -r option... (Not really,
but many users have had questions about the exact behavior there.)
The second rev does not go to HEAD if there is no -r option - just to
add confusion to the mix. If you use -r with one revision the second part (:M)
defaults to HEAD. (As per the help text in section 1)
So the behavior of diff seems to be correct with the only confusing bit being
what happens when you specify a -r with only a single revision *and* --old/--new
with peg revision on --new...
