[PATCH v4] clone: update submodule.recurse in config when using --recurse-submodule

["Mahi Kolla via GitGitGadget" <gitgitgadget@gmail.com>]

From: Mahi Kolla <mahikolla@google.com>

When running 'git clone --recurse-submodules', developers might expect various other commands such as 'pull' and 'checkout' to also run recursively into submodules. Set 'submodule.recurse' to true when 'git clone' is run with '--recurse-submodules'.

Since V1: Updated test and 'git clone' man page. Also updated commit message.
