- Revert `quilt fork' to how it originally worked: fork the

  *topmost* patch, not the next unapplied patch. Adapt the
  test suite accordingly.
- Add flag to backup-files.c to make sure that files in the
  working tree have a link count of at most one. Use this where
  appropriate.
- Fix a bug in `quilt snapshot': Taking snapshots caused files
  to get link counts bigger than one, so modifying them could
  cause multiple files to get modified. Speed up the command,
  too.
- Update the documentation. Add example1.test from the
  documentation.
