That doesn't look right.  If you want to ensure every backend sees the
variable when needed, place it into vc-hooks.el (this is the
always-loaded portion of VC).  It needs to have a good doc string
though.  Not having followed the discussion until now, I have hardly any
idea what the variable is supposed to do.  The doc string suggested in
an earlier patch:

  "Regular expression to identify remote folders"

isn't much help either.  ("Folder" is not an Emacs term, to begin
with.)  Please clarify.  Also, if this is a general mechanism to
identify directories on remote hosts, I wonder if only VC is concerned
with it.  Perhaps the regexp needs to go to a different place
