[PATCHv3 0/5] repo-local env vars handling

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

Ok, the Git GUI + submodule fix is shaping up in a pretty much more
general thing. In this third iteration, the patch has been augmented by
two important patches:

* the first patch defines a static list (const char *const []) holding
  all the repo-local environment variables. The list is not used yet,
  just defined
* the third patch adds a rev-parse (I couldn't think of a better place)
  option to list these variables (just the names, not the values)

The connect and sh-setup patches have obviously been adapted to use
the new provided features. The last patch didn't change, which in
particular means that Jens Lehmann's C-side submodule fix is still
valid, although it might benefit from being reworked to exploit the
static list exposed by this patchset.

Giuseppe Bilotta (5):
  cache: 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
