It might. On the other hand, every warning that -Wduplicated-branches generated 
for grep (3 warnings) and for Emacs (4 warnings) was a false alarm. Yes, we can 
pacify GCC for each false alarm, but so far -Wduplicated-branches' cost/benefit 
ratio has been infinity and this is not a good sign.

I wouldn't bother changing kwset.c back, unless there's a need; we both have 
better things to do that worry about this.
