Bash Version: 4.2
Patch Level: 8
Release Status: release

Description:
        When  running "echo [A-Z]*" , it shows all files/dirs of current
    directory, not only those starting with capital letters. I tried
    different locales such as: POSIX, C, en_US, pt_BR

Repeat-By:
    $ mkdir a && cd a
    $ touch a b c; mkdir D E F
    $ echo [A-Z]*
    b c D E F
    $ echo [a-z]*
    a b c D E F



Fix:
