* Always the first difference - the current behavior seems be jumping to the cursor position when the file was last opened for edition. Sometimes some differences are missed because the buffers open with only the last differences on the screen.

* Move the cursor to the first difference - the current behavior seems to be leaving the cursor at the diff window. I've found that most of the time it is necessary to check the changes on many files, and using \dj and \dk leaves the cursor on diff window, so it is necessary to move back to the diff windows.

The current behavior uses `:bd` to close a diff window after it is displayed on
the screen, which causes any other windows displaying that file to be closed.

The option g:DirDiffBufferDelete allows to use `:q` instead. In this case the
`:diffoff` is also necessary to avoid subsequent diffs to be displayed
incorrectly.
