I hate to burst your bubble, but that is just not true.  I just looked
at the source for mv in Ultrix-11 V3.1 which is a DEC derivative of AT&T
Version 7 Unix dating back to at least 1984 and what it does is:
1) determine if source is a directory then it can only rename, not move
2) attempts to link source and destination if this fails use "/bin/cp"
3) unlink source
