针对于Git的第一个patch已经进入主库

主要是让git-gui能够在小的屏幕上，正常显示其“提交”与“推送”按钮。在Fedora12中，由于默认采用了比较小的gnome窗体，使原来的实现就能够显示那些按钮，咳。补丁的提交经过4次修正，主要是对英语描述的修正；-）。

    git-gui: adjust the minimum height of diff pane for shorter screen height
   
    When the main window is maximized, if the screen height is shorter (e.g.
    Netbook screen 1024x600), both the partial commit pane and the status bar
    are hidden. The diff pane is resizable, so that it can use less vertical
    height, allowing the overall window to be shorter and still display both
    the entire commit pane and status bar.
