I am not sure it is exactly a bug.  It seems to be dependant on how
find processes its parameters - in order of occurance.   A similar effect
can be seen with some other parameter combinations such as putting -print
in the wrong place - you can get all files in the system printed or none
rather than just what you want.   Possibly the man page needs to be
updated to make the effect of parameter order clear.
