Suppose the "Unstaged Changes" pane contains a list of files, and one of them is selected (i.e., that diff is currently being displayed). If one clicks on the icon to stage the change, git-gui clears the diff and one has to click on another filename to see the next diff in the list.

This patch changes that behaviour. If one clicks on the icon to stage (or unstage) the file whose diff is being displayed, git-gui will move on to the next filename in the list and display that diff instead of a blank diff pane. If the selected file was at the end of the list, the diff pane will display the previous diff instead; if the selected file was the only one listed, the diff pane will become blank.

If no diff is currently being displayed, this patch changes nothing.

[PATCH] git-gui: Don't select the wrong file if the last listed file is staged.

Johannes Sixt noticed that if the last file in the list was staged, my earlier patch would display the diff for the penultimate file, but show the file _before_ that as being selected.

This was due to my misunderstanding the lno argument to show_diff.

This patch fixes the problem: lno is not decremented in the special case to handle the last item in the list (though we still need to use $lno-1 to find the right path for the next diff).
