For each argument, a local variable named name is created, and
assigned value. The option can be any of the options accepted
by declare. When local is used within a function, it causes the
variable name to have a visible scope restricted to that func‐
tion and its children. If name is -, the set of shell options
is made local to the function in which local is invoked: shell
options changed using the set builtin inside the function are
restored to their original values when the function returns.
It's supposed to let you make things like "set -f" local to the function
in which they appear. I've never actually used it yet.
