title: Force SVN (tortoise) to check-in a file to update Revision
body: <p>I have a file that contains the revision placeholder in the form:</p>
  
  <pre><code>$Rev: 123456 $
  </code></pre>
  
  <p>The file is checked-in only if it changes, so, if I want to commit it just to update the revision number, I am forced to add a fake change (example: adding a space, a new line, something like that) in order to been able to see it in the change-list and commit it, obtaining the result I am looking for.
  Even if I modify the revision flag, writing for example:</p>
  
  <pre><code>$Rev: 0 $
  </code></pre>
  
  <p>SVN is "smart" enough to ignore this change...</p>
  
  <p>Is there a (clean) way to simply tell SVN (tortoise) that the file must be checked in without using these "tricks"?</p>
  
  <p>NOTE: This is needed because the revision number in used in the build. This allows us to clearly identify the version of the build when it is run.</p>
