In Emacs, I found -Wduplicated-branches to be useless and I disabled it. Since 
it's finding only false alarms in grep, too, I suggest that we disable it by 
default at the Gnulib level. My impression is that for GNU code, 
-Wduplicated-branches is mostly just the compiler saying "Look how smart I am!" 
rather than something that's helpful in finding real bugs.
