+This loads the "defaults.vim" file in the $VIMRUNTIME directory.  This sets up
+Vim for how most users like it.  If you are one of the few that don't, then
+comment out this line.  The commands are explained below:

+
+This tells Vim to keep a backup copy of a file when overwriting it.  But not
+on the VMS system, since it keeps old versions of files already.  The backup
+file will have the same name as the original file with "~" added.  See |07.4|
+
+This also sets the 'undofile' option, if available.  This will store the
+multi-level undo information in a file.  The result is that when you change a
+file, exit Vim, and then edit the file again, you can undo the changes made
+previously.  It's a very powerful and useful feature, at the cost of storing a
+file.  For more information see |undo-persistence|.
+
+The "if" command is very useful to set options
+only when some condition is met.  More about that in |usr_41.txt|.

+This makes Vim break text to avoid lines getting longer than 78 characters.
+But only for files that have been detected to be plain text.  There are
+actually two parts here.  "autocmd FileType text" is an autocommand.  This
+defines that when the file type is set to "text" the following command is
+automatically executed.  "setlocal textwidth=78" sets the 'textwidth' option
+to 78, but only locally in one file.
+
+The wrapper with "augroup vimrcEx" and "augroup END" makes it possible to
+delete the autocommand with the "au!" command.  See |:augroup|.
