It'll work with one `else` in the mix.

Roman.
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.
