This new option will allow the user to not only update the work tree of
the superproject according to the merge result but to also update the
work tree of all initialized submodules (so they match the SHA-1 recorded
in the superproject). But this commit only adds the option without any
functionality, that will be added to unpack_trees() in subsequent commits.
