Positional Parameter Settin in function

[Brandon S. Allbery]

As quoted from <570024 at hpsemc.HP.COM> by gph at hpsemc.HP.COM (Paul Houtz):

+---------------

Feature.  Positional parameters are local to a function; as "set" sets
positional parameters, its effect is lost when the function exits.

Under (System V) /bin/sh, positionals are global:  "set" works the way you
expect, but calling a function with arguments destroys the shell's global
parameters -- which has caused me considerable annoyance at times.

I prefer the ksh implementation.
