Update the documentation accordingly. Some terminology: - Active is defined in gitsubmodules(7), it only involves the configuration variables 'submodule.active', 'submodule..active' and 'submodule..url'. The function submodule.c::is_submodule_active checks that a submodule is active. - Populated means that the submodule's working tree is present (and the gitfile correctly points to the submodule repository), i.e. either the superproject was cloned with ` --recurse-submodules`, or the user ran `git submodule update --init`, or `git submodule init []` and `git submodule update []` separately which populated the submodule working tree. This does not involve the 3 configuration variables above. - Initialized (at least in the context of the man pages involved in this patch) means both "populated" and "active" as defined above, i.e. what `git submodule update --init` does. The --recurse-submodules option mostly affects active submodules. An exception is `git fetch` where the option affects populated submodules. As a consequence, in `git pull --recurse-submodules` the fetch affects populated submodules, but the resulting working tree update only affects active submodules. In the documentation of `git-pull`, let's distinguish between the fetching part which affects populated submodules, and the updating of worktrees, which only affects active submodules.
