vim-patch:7.4.2015

Problem:    When a file gets a name when writing it 'acd' is not effective.
            (Dan Church)
Solution:   Invoke DO_AUTOCHDIR after writing the file. (Allen Haim, closes
            vim/vim#777, closes vim/vim#803)  Add test_autochdir() to enable 'acd' before
            "starting" is reset.
