Similar thing happens when the right half reaches the bottom. Does Vim avoid this problem? Also, what about scrollbars and cursors - do you get a single one (as I want) or two of each (as I get in emacs)? Finally, is there an emacs-like keyboard binding for Vim (the reverse of emacs' "viper" mode)?
