This may be a feature.  The kernel rejects attempts by non-root to set
the sticky bit for non-directories.  mv(1) has no idea that the problem
is caused by the sticky bit, so it doesn't try another chmod() to set
the other bits.  The sticky bit has no direct effect for non-directories,
so perhaps is was being used by root to inhibit moving files :-).
