Thanks, Paul and Bruno. That looks fine.
I confirmed that the diagnostic is elicited only when the offending
pattern is specified on the command line and not as an argument to the
-e option. I.e., this still elicits the diagnostic:

$ :|grep -e '\-x'
grep: warning: stray \ before -

Once you push that (and assuming you have nothing else pending), I'll
prepare another pre-release snapshot.
