This is interesting. Using that makes grep (and I suppose all the utilities 
that honour that) ignore options after operands, which is what guideline 9 
says.

"All options should precede operands on the command line."

with "should" interpreted as "shall" as explained later. But then what's the 
meaning of rule 14, and how would that be supposed to be enforced when 
POSIXLY_CORRECT is set? It would seem to be clashing with 9.

Thanks.
