nits:

* Git's commit messages usually use the present tense to describe the
  behavior of Git in absence of a patch, as though writing a bug report.
  They use the imperative mood to describe what the patch will do, as
  though commanding the code to do better.
* spelling: s/CLi/CLI/; s/tigger/trigger/
* please also wrap lines consistently

That would make

	"git pull" supports a --recurse-submodules option but does not parse the
	submodule.recurse configuration item to set the default for that option.
	Meanwhile "git fetch" does support submodule.recurse, producing
	confusing behavior: when submodule.recurse is enabled, "git pull"
	recursively fetches submodules but does not update them after fetch.

	Handle submodule.recurse in "git pull" to fix this.

Can you add a test to avoid future changes causing this to regress?
See t/t5572-pull-submodule.sh for some existing tests to get
inspiration from.

The rest looks good.

Thanks for working on this,
