Please read the original question again. The OP is asking for a diff
between the modified file before update and the modified file after
update. You are comparing the repository with the modified file after
update. And he is asking for a way to go back to his pre-update state
as if the merge never happened. There is no way in subversion to do
either of those things without first making a copy manually.
