A few nits to pick:

Why not assign directly to recurse_submodules?  The variable r is only
set once and read once, and doesn't have a particularly descriptive name
that would justify having it.

builtin/fetch.c::git_fetch_config(), builtin/push.c::git_push_config()
and submodule.c::git_default_submodule_config() do the same, and I can't
infer why for them either.

And why fall through to git_default_config() here even though we know
that it won't match "submodule.recurse" again?  Config functions are
usually exit early on finding a match, as the "rebase.autostash" handler
above does.
