Minor bug declaring arrays of integers: dcl -ai=>broken, dcl -ia=>ok

[Linda Walsh]

In order to declare an array of type int (or an integer array)
I first tried:

> declare -ai -g foo=(1 2 xx 3)
> echo "${foo[@]}"
1 2 xx 3   <---------incorrect

So then tried:


> declare -ia -g foo=(1 2 xx 3)  
> echo "${foo[@]}"
> 1 2 0 3  <---------correct!

It seems 'declare' is sensitive to the order of its options in an
undesirable way -- i.e. for typed arrays, the -i should be
allowed either before or after the -a (or -A for hashes).

That makes me wonder if the "-g" worked.
I.e. -- if "-g" after "-ia" works, and whether I need "-g -ia"
(or "-gia")
