  18  +++ indicates that the appropriate manual has already been updated.
  19  --- means no change in the manuals is called for.
  20 When you add a new item, please add it without either +++ or ---

  37 ** If the gpm mouse server is running and t-mouse-mode enabled, Emacs uses a
  38 Unix socket in a GNU/Linux console to talk to server, rather than faking events
  39 using the client program mev.  This C level approach provides mouse
  40 highlighting, and help echoing in the minibuffer.
  41
  42 ** The new variable next-error-recenter specifies how next-error should
  43 recenter the visited source file.  Its value can be a number (for example,
  44 0 for top line, -1 for bottom line), or nil for no recentering.
