In your opinion are your changes more portable across a wide range of systems?

I didn't think at portability :-). I only made it working for me. Maybe there are other persons out there who do have some old versions too - so they can use this patch.

Well, I found that i--/i++ don't work with bash-2.03 (present about everywhere) but i=i-1 or i=i+1 work well. So at least, for portability, this could be rewritten as "while (( i=i-1 )); do".
