The file name never changed.

No.

But it seems that my problem is a known limitation:

  Verify that the object's location (path-wise) in PEG-REV is the same
  as it is in OPERATIVE-REV. If that's the case, at least the two
  locations are known to be directly related, so perform the requested
  action on the location in OPERATIVE-REV. Otherwise, relatedness was
  not established, so error out with a loud complaint that no viable
  location was found. (Someday, we expect that Subversion will be able
  to handle this usage scenario with more flexibility and grace.)

This is the latter case.

One problem is that it seems to be impossible to specify an object
that was removed from the current directory (actually its ancestor),
just by using its name and some revision.

And in case you didn't see...
