[ef]grep I guess my basic issue is that I don't understand the benefit of the new warning. It causes a lot of trouble. What is the countervailing positive benefit?
$ grep '\Q' /dev/null grep: warning: stray \ before Q It would be nice to be able to turn those off too. (It hit me today.) Those warnings are even worse than [ef]grep in a way, since they are not changeable just by editing the scripts, but built-in behavior. We've been moving away from environment variables like GREP_OPTIONS, though, for security reasons. Personally, I don't see a security issue with the putative GREPWARNINGS? Unlike GREP_OPTIONS, whose removal is understandable (though it sure was convenient, alas). --karl
