title: CVS remove sticky tag without update
body: <p>CVS is really driving me crazy! </p>
  
  <p>Is there any trick to remove sticky tags without updating file contents? 
  I know of 'cvs up -A' but this also changes my files. </p>
  
  <p>Or the other way round: 
  Is there any way to update a complete directory to a previous date without setting sticky tags in the first place? </p>
  
  <p>Background: 
  I use a working copy that is versioned both with CVS and HG and I messed it up, so I wan't to go back to the latest point where it was in sync and then check what would come in from CVS. </p>
  
  <p>thanks and regards. </p>
