If you want 'undofile' only for certain files, you will notice that 'undofile' cannot be set in a modeline, or once the buffer is loaded (because an existing undo file will not be loaded then).  Bram suggests to use a BufReadPre autocmd which sets 'undofile' before the buffer is loaded.  This script does the steps for you. Usage: :SetUndoFile[!]   execute :setlocal undofile, install a BufReadPre autocmd for the current file name and also maintain a plugin file "plugin/undofile_autocmds.vim" that enables all such autocmds at next startup of Vim.   This means you can execute this command once for the current file and then never ever again -- FIRE AND FORGET ;)   The plugin file (if not found in the runtimepath) is stored in the first directory of the runtimepath (which must contain a "plugin" folder).  Older Vims will ignore the plugin.   With [!], ignore if 'undofile' is already set. :UnsetUndoFile   opposite of :SetUndoFile.  Does :setlocal noundofile, removes the autcommand and the autcommand entry from "plugin/undofile_autocmds.vim"; finally it executes :DelUndoFile. :DelUndoFile   delete the undofile for the current buffer.  Fails silently. PLEASE REPORT BUGS

Note: With Vim 7.3.392 or newer, you can set 'undofile' in the modeline!  No need for this script then ... (2012 Jan 28) requires the persistent_undo feature (since Vim7.3) :source this script when needed, or drop it in your plugin folder
