REVISION SUMMARY
  When copy information is stored in changesets, it gets lost on
  amend. We didn't notice that until now because our users at Google
  have the config set to `compatibility`, which means copy information
  is stored in both changeset and filelogs.

REPOSITORY
  rHG Mercurial

BRANCH
  stable
