That is correct, assuming the file names have not changed. Where's the
contradiction? For there to be a contradiction I would have had to have
said something that said the above was incorrect.

Ahh, yes... that's what I've been trying to explain; the peg revision
also has the effect of setting the HEAD revision back to the specified
peg, so you check out the files ( both names and content ) as of the
specified peg revision, which is why -r 5 and @5 give the same results
if the names have not changed.
