Re: [PATCH] completion: remove duplicate block for "git commit -c"

This was caused by a mechanical mismerge at d931e2fb252e (Merge
branch 'mp/complete-paths', 2013-02-08), it seems.  The side branch
fea16b47 wanted to add this block, of course, but the same fix was
done independently in 685397585 already.

Thanks for catching it.
