 A couple of notes on this...
 
 
 * It does not happen with, e.g., ZFS, so it appears to be UFS-specific.
 
 * When doing cp -pR, it does not happen.
 
 * Along these lines, I tried moving files and dirs *across* file
 systems, and it does not happen.  So it's the case of moving a dir to
 another dir in the *same* fs that invokes the issue.  Since moving
 across filesystems (according to the man page) uses "rm -f dest && cp
 -pRP source dest && rm -rf source" rather than rename, this makes sense.
 
 
 P.S.  I used the web-form to submit the bug, so the text box must treat
 the text as one long line (hence the 417 character line).
