I agreed that once we have the ability to do so, autoupdating any
initialized submodules should be automatic and non-optional.  However,
making it optional during a transition period while the ability gets
fleshed out would make sense too (so checkout-mode folks can opt in
before we clobber the local-branch folks ;).
