Which means that far from deprecating "sync", we should strive for
imprinting the need for the use of the subcommand deeper in users'
minds.  I wonder if it makes sense to make sure that .gitmodules
file starts with something like

	# Note that after updating this file, you may want to
	# run "git submodule sync" so that the URL for the remote
	# repository etc. are propagated down.

when we create it (via, say "git submodule add")?  Or alternatively,
warn the users when "git status" notices a local modification, or
something along that line?
