Although its clear the original question is about BSD, it should be noted that
SystemV has just such a utility:  dcopy(1M).  It's man page claims it will
deflate large empty directories and place file blocks with optimal rotational 
gap.  Also subdirectories are placed at the beginning of a directory in hopes
of speeding depth first directory searches.  Given that AT&T went to the 
trouble to do this, cp(1) sounds too easy (and no directory re-organization
is done to the best of my knowledge.)
