    Add a -D option to touch, which acts like the -d option added to
    chmod/chown/chgrp (probably others) in the not too far distant past,
    and causes the operation to be a no-op if no actual change would be
    made (avoiding updating the file's ctime for no reason).

    That is, with touch, -D causes no modifying sys call to be made to
    a file if that file's atime and mtime are already set to the values
    that would be used.   A common case for this is when a "-r ref-file"
    is also a target file for the operation.

    Unfortunately -d was already taken in touch, so next best available is -D.
