dir.

- Changed get_backup_name() to verify the backup path, and make any
  missing directories.  This avoids accidental use of a symlink as a dir
  in a backup path, and gets rid of any other non-dirs that are in the
  way.  It also avoids the need for various operations to retry after
  calling make_bak_dir(), simplifying several pices of code.
- Changed create_directory_path() to make_path(), giving it flags that
  lets the caller decide if it should skip a leading slash or drop the
  trailing filename.
- Mention when we create the backup directory, so the user is not caught
  unaware when rsync uses a directory they didn't expect.
- Got rid of some dir-moving backup code that is not used.
- Added a little more backup-debug output.

rsync to associate the wrong ACL/xattr information with received files.

- Mention the switch from MD4 to MD5.
- Mention the default for the --log-file-format option.

Makefile-updating rule to run ./config.status.

- Avoid sending MSG_NO_SEND to the generator.
- Check if the file is wanted before discarding the batched data.

Fixes issue mention in bug #5615.

- Implement --ignore-missing-args.
- In the absence of --*-missing-args, a missing source arg is an
  FERROR_XFER, but doesn't need to be an IOERR_GENERAL.
- Revise the man page.

shortening some code.  Improve comments and make other minor cleanups.
Based on a patch that Matt McCutchen posted to the mailing list.

This avoids a problem where an extra message from the sender
could give the generator time to start sending data that will
not be understood by the sender's use of read_msg_fd().

This avoids a transfer error in the receiver.
