I don't think this can be done reliably without completely cleaning
your Git clone (with Git commands), in addition to "make distclean"
etc.  Emacs branches diverge too quickly for this to work (like it
does with some other projects); it's why I use two separate directory
trees to track both branches simultaneously.
