    Rules for maintenance:
-   
+
    * Anyone can add text to this document.  Do not spend very much time
    on the wording of your changes, because your text will probably
    get rewritten to some degree.
-   
+
    * The maintainer will go through Misc/NEWS periodically and add
    changes; it's therefore more important to add your changes to
    Misc/NEWS than to this file.  (Note: I didn't get to this for 3.0.
    GvR.)
-   
+
    * This is not a complete list of every single change; completeness
    is the purpose of Misc/NEWS.  Some changes I consider too small
    or esoteric to include.  If such a change is added to the text,
    I'll just remove it.  (This is another reason you shouldn't spend
    too much time on writing your addition.)
-   
+
    * If you want to draw your new text to the attention of the
    maintainer, add 'XXX' to the beginning of the paragraph or
    section.
-   
+
    * It's OK to just add a fragmentary note about a change.  For
    example: "XXX Describe the transmogrify() function added to the
    socket module."  The maintainer will research the change and
    write the necessary text.
-   
+
    * You can comment out your additions if you like, but it's not
    necessary (especially when a final release is some months away).
-   
+
    * Credit the author of a patch or bugfix.   Just the name is
    sufficient; the e-mail address isn't necessary.  (Due to time
    constraints I haven't managed to do this for 3.0.  GvR.)
-   
+
    * It's helpful to add the bug/patch number as a comment:
-   
+
    % Patch 12345
    XXX Describe the transmogrify() function added to the socket
    module.
    (Contributed by P.Y. Developer.)
-   
+
    This saves the maintainer the effort of going through the SVN log
    when researching a change.  (Again, I didn't get to this for 3.0.
    GvR.)
