title: Is it safe to remove bundles in strip-backup folders?
body: <p>Recently I have rewrote a lot of history (Forgive me Father, for I have sinned). Our old repository had a lot of sensitive information as well as unnecessary merges (up to 20 anonymous branches running simultaneously and being merged back indiscriminately), so I have striped several commits, pruned dead branches, rebased / squashed commits, rolled back unnecessary merges, created bookmarks, etc.</p>
  
  <p>We now have a clean repo. I have also run unitary tests along several revisions to make sure that I haven't broke anything import. Yesterday I've forked the old repo (for backup purposes) and pushed the clean repository upstream. We are a small team and synchronizing changes was not a problem, every developer in my team is already working with the new repo. </p>
  
  <p>Anyway, my <strong>local</strong> repository now have a <code>.hg/strip-backup</code> folder of around 2 Gigabytes.
  From what I was able to understand, this folder contains backup bundles for every one of the destructive commands that I have run. I no longer need those.</p>
  
  <p>My question is: Is it safe to remove the bundles inside <code>.hg/strip-backup</code>? Or will I corrupt my local repository if I delete those files?</p>
  
  <p><strong>Bonus question</strong>: Is there a built-in mercurial command to remove backups or should I just use <code>rm .hg/strip-backup/*</code>?  </p>
