Again, I point out the distinction between two meanings for "no files
were affected":

"there were no differences to merge"
"all the differences were rejected"

The first case is certainly a no-op, and (surely?) everyone would agree
that there's no value in recording anything about it.

The second is a conscious decision (startling, in your extreme case, but
hey, that's what extremities are for!). You can only argue that no
record should be made of this (startling) event if you can also argue
that no subsequent use would be made of the record. And I think that's
not true, here: the next merge including this range of revisions
will/should be affected by this record.
