 	* vc-dispatcher.el: New file, separates out the UI and command 
 	execution machinery from VCS-specific logic left in vc.el.  The
 	separation is not yet completely clean, but it's a good start.

+	* vc.el: This file is about 1700 lines shorter now.  Obsolete

+	it guarded against a log length limit that has probably been
+	obsolete for 15 years (!).
