I really think we should not encourage unportable code like that by
giving an example in our manual page.
I'm even tempted to say that you should leave the "-exec rm {} \;"
example alone. The + here only works because rm(1) accepts multiple
file arguments.
And I don't understand the sentence about recursively removing
non-empty directories; rm(1) doesn't remove directories unless you use the
-r option!
