[PATCHv4 0/6] repo-local env vars handling

Changes from the previous iteration:

* moved the static list to environment.c, per Junio's suggestion
* added a local_repo_env_size constant. It's cheap, and it helps
  prevent some horrible gimmicks when the list size needs to be known
  without walking it
* a variation on Junio's variation on Jens' patch for submodule.c,
  using the static list _and_ the size constant.

Giuseppe Bilotta (6):
  environment: static list of repo-local env vars
  connect: use static list of repo-local env vars
  rev-parse: --local-env-vars option
  shell setup: clear_local_git_env() function
  submodules: ensure clean environment when operating in a submodule
  is_submodule_modified(): clear environment properly
