Now I see that findutils has two ways around this: using -false or using
the "," comma operator. You can use the comma to perform multiple
independent tests, for example:
find /etc \( -name "[aeiou]*" -fprint vowel.6 , -mtime -100 -fprint recent.6 \)
has the same results as:
find /etc \( -name "[aeiou]*" -fprint vowel.5 -false \) -o \( -mtime -100 -fprint recent.5 \)
(and the timing is about the same from few tests I did on a couple
filesystems).
I will just use -false for now instead of also coding "comma" support.
