Array name expansion in bash-4.3

[Corentin Peuvrel]

Hello,

I think I found a bug in bash-4.3.

An example should be self-explanatory :

bash-4.2 :
$ arr=( idx1 idx2 )
$ i=arr[1]
$ echo ${!i}
idx2
$ echo ${!i/x/X}
idX2

bash-4.3 :
$ arr=( idx1 idx2 )
$ i=arr[1]
$ echo ${!i}
idx2
$ echo ${!i/x/X}
idX1

If we use pattern substitution (or removing prefix/suffix pattern, ...) 
with an expansion of an array name which contain a non zero index, it 
will still use the index 0.

Thank you,
