because it's a simplier way to get the list into a variable
because the script gets much clearer
because it is not safe to rely on stderr since it is supposed to display 
errors, which it might do as well
because he would get the list of the files that have really been 
compressed, not just the processed ones
because the overhead may not be worth the complication of trying to do 
both things at the same time
because he might as well never use the v option (it's not useful in my 
proposition either, and it would even reduce the overhead)

because it is another way to do it and nobody had proposed it before
