More sophisticated handling of file mode and symlinks when saving:
  - File mode used to be reset to umask when backups are enabled, now it's
    correctly copied from the original file (with symlinks followed)
  - Symlinks used to be converted to regular files when backups are enabled,
    now the symlink is preserved, and the file it points to is modified
    instead. Backup filename is related to the filename of the symlink.
