REVISION SUMMARY
  If you turn on copies in changesets and write a commit with a copy,
  then turn it off and amend the commit while undoing the copy, the
  invalid copy information will remain. The read path doesn't crash in
  invalid copy data, but it seems better to not produce the invalid
  data.

 The entries should be written to extras even if they're empty (so the client
 won't have to fall back to reading from filelogs)
