BTW, Sun says their grep complies with POSIX.1 as well:
STANDARDS
The grep utility is compliant with the IEEE Std 1003.1-2008 (“POSIX.1”)
specification with the exception of -s option being the same as -q in
current implementation for historic reasons. The flags [-AbBChHrRw] are
extensions to that specification.
So I'm not sure whether or not the bug lies in grep or posixly-correct
GNU grep.
