[PATCHv3 0/4] A reroll of sb/submodule-blanket-recursive

v3:
* rerolling only the top-4 patches of sb/submodule-blanket-recursive.
  (base: 1d789d089280539ca39b83aabb67860929d39b75)
* fixes function declarations that should be static, thanks Ramsay!

v2:
* A reroll of sb/submodule-blanket-recursive.
* This requires ab/grep-preparatory-cleanup
* It changed a lot from v1, as in v1 the tests did not work,
  hence the code was broken. Now it actually works.
* it also includes grep, fetch, push in addition to plain working tree
  manipulators.

Thanks, Stefan

Stefan Beller (4):
  Introduce 'submodule.recurse' option for worktree manipulators
  builtin/grep.c: respect 'submodule.recurse' option
  builtin/push.c: respect 'submodule.recurse' option
  builtin/fetch.c: respect 'submodule.recurse' option
