git fetch without --recurse-submodules option

Hi, With git pull or git fetch without specifying --recurse-submodules, what is the default action? It seems git fetches submodules wtihout specifying --recurse-submodules. If this is not clear, please update documentation.

In git pull document --recurse-submodules option, it tells users to see git-config(1) and gitmodules(5), but does not tell users to refer to git fetch --recurse-submodules for the meaning of the switches.
