[PATCHv2 0/2] clear environment for submodules

[Giuseppe Bilotta <giuseppe.bilotta@gmail.com>]

Second (or maybe actually third) iteration of the series to ensure that
submodules work correctly when repo-local environment is set. The only
thing changed from the previous iteration is an extra variable in
clear_local_git_env() to bring it up in sync with the list in git_connect(),
and also the addition of CONFIG_ENVIRONMENT in git_connect() itself.

I had considered making a static list of these variables somewhere, but
making it accessible to both the built-ins and shell scripts (something à
la git rev-parse --local-git-env maybe?) is a little over my head at the
moment (not much free time to dedicate to git, sadly). Also I'm not sure
the extra git call needed to get the list would be worth it.

  shell setup: clear_local_git_env() function
  submodules: ensure clean environment when operating in a submodule
