Comment 0 for bug 137976

From #bzr:

<dato> running `bzr upgrade` in a lightweight checkout makes a backup of
       the light .bzr, not of the real .bzr. would that be considered a bug?
<lifeless> no, because its upgrading the lightweight checkout
<dato> but it changes the "remote" branch as well
<lifeless> ok thats a bug
<lifeless> it should only alter the lightweight checkout
<dato> okay, I'll double-check it does that, and file one

To reproduce:

  % bzr init --dirstate branch
  % bzr info branch | head -1
  Standalone tree (format: dirstate)

  % bzr checkout --lightweight branch checkout
  % cd checkout && bzr upgrade
  [...] finished

  % cd ../branch && bzr info | head -1
  Standalone tree (format: dirstate-tags)
