I\'ve been using various source control systems for a while, but when it comes to reverting changes I\'m not yet an expert. Can someone help given this scenario:
I think you need to reverse merge first between 5:4, then revert the correct file
svn merge -r 5:5 http://svn.example.com/repos/calc/trunk
svn revert correctfile
you probably end up with at weird state on the 2buggy files That you can hopefully can solve manually.
