title: Reverting a part of the commit in SVN
body: <p>I have merged revisions 1,2,3 from branch A to branch B and committed the same in a single commit.
  Now, I need to revert back only revision 2 from branch B.</p>
  
  <p>It is difficult to revert this commit and redo the merge as there lot of commits that have been made after this.</p>
  
  <p>Is there any option to do it other than manual compare and reverting the changes?</p>
