Follow-up Comment #1:

POSIX 2008 was specifically modified to allow GNU find's behavior of an
optional path component (but you are correct that it is a violation of POSIX
2001).

http://pubs.opengroup.org/onlinepubs/9699919799/utilities/find.html

"If the first operand starts with a '-' , or is a '!' or a '(' , the behavior
is unspecified."

I'm considering closing this as WONTFIX - it is not worth our efforts to
cater to older POSIX to require failure.  And the only other way to report
failure is by the addition of extra parameters or by the presence of
POSIXLY_CORRECT - which _won't_ catch the non-portability aspect in the common
case when you are not using these extra options.
