Git + ZendFramework submodule = modified: src/vendor/zend because of CRLF: the workaround

gistfile1.txt

It's a shame, but https://github.com/zendframework/zf2 contains dozens of files with CRLF issues.
If like me, you set your Git core.autocrlf to true, then your ZendFramework submodule is always modified:

    $ git status
    # On branch master
    # Changed but not updated:
    #
    #       modified:   src/vendor/zend

To fix it, you can set Git core.autocrlf to false *only for this submodule*.

Edit `path/to/zf-submodule/.git/config`

    [core]
        autocrlf = false
        ...

That's all! Git no more bothers you with the infamous CRLF issues of ZendFramework.
