title: --full-history flag in TortoiseGit Show Log
body: <p>I'm using git + tortoisegit. 
  When I see show log of repository I see my commit that has file1. 
  But when I show log of file1 I cannot see this commit in the log history.</p>
  
  <p>According to this advace <a href="https://stackoverflow.com/questions/28303805/git-log-filename-doesnt-show-commit-but-git-log-shows-commit-that-edited-the?answertab=votes#tab-top">git log &lt;filename&gt; doesn&#39;t show commit, but git log shows commit that edited the file</a>
  I use --full-history flag (git log --full-history --author-date-order file1) in the console and this command shows my commit.</p>
  
  <p>How can I apply this flag when  I try to see log by tortoisegit on particular file?</p>
  
  <p>Could you please help me? Thanks.</p>
