Thanks, it's better that way. Still, it seems to me you don't always
clean the variants properly, you should do some sort of "goto end" in
all cases instead of simply returning. Also renaming the function
parameters in most cases is not necessary. I'd also suggest to do a
separate patch for each function, especially since in some functions a
bit of restructuring will be needed to cleanup properly on error.
