[PATCHv2 0/3] Teach shell scripts to be quiet

The main goal of this is to teach git-am and git-rebase to be quiet. To do that, I've implemented a generic say function in git-sh-setup so that script writers can implement a quiet option by setting GIT_QUIET and using say instead of echo.

git-stash is still left out, but hopefully this makes that easier for someone else later.

Changes since v1:
    - introduction of say()
    - migration of submodule and repack

Stephen Boyd (3):
  git-sh-setup: introduce say() for quiet options
  submodule, repack: migrate to git-sh-setup's say()
  am, rebase: teach quiet option
