VC doesn't really need the info.  It only uses it because of its
original mistake to use dired (and hence `ls').  Once this mistake is
corrected it won't need it any more.

Where else, then?  In simple.el or subr.el or some other global file.
Then VC backends can add to that variable and so can any other
elisp package.  This way speedbar doesn't need to refer to any of
those packages.
