title: See complete history of changes in smartGit
body: <p>Is there a way to easily trace all the changes made to a file in smartGit?
  I have looked around without success..</p>
  
  <p>I want to be able to see the current version (v0) against the version before that (v-1). Then I want to be able to see two earlier versions in comparison to each other (as in v-1 against v-2 or v-1 against v-3)</p>
