I'm happy with it as it is now, it seems clean.  I've always tended to 
be a good Protestant and do:

    ...
    shift
    ...
    ...
    while [ $1 ]
    ...


... get the shifting done ASAP, but the more I think about it the more I 
like:

    ...
    while [ $2 ]
         shift
    ...

... more Catholic ... do it when you need to do it.   The function is 
quite a bit simpler that way.  Cross bridges when I get to them.
