Re: submodule update and core.askpass

BTW, a workaround is to pass a path to askpass script in the GIT_ASKPASS
environment variable.

git -c core.askpass=pass.sh clone main-repo
cd main-repo
git submodule init
git submodule sync
git -c core.askpass=pass.sh submodule update

The last command asks for a password interactively. 

I've run bisect, it seems like it started failing from commit
be8779f7ac9a3be9aa783df008d59082f4054f67. I've checked: submodule update
works fine in 1.8.5.rc2 with removed call to clear_local_git_env.

Aside from GIT_CONFIG_PARAMETERS, which this needs ...

Yes, if I understand GIT_CONFIG_PARAMETERS correctly we should not
clean it as the user explicitly asked us to use that setting.

..., I wonder if we
should also let other variables pass through.  For example, if the user
went out of their way to set GIT_ALTERNATE_OBJECT_DIRECTORIES, shouldn't
we also respect that?

Hmm, I'm not so sure. Does the user really want the setting of
GIT_ALTERNATE_OBJECT_DIRECTORIES to be honored inside the submodule
too or would he want a different setting (including none)? I suspect
different users would give different answers. And wouldn't a working
GIT_CONFIG_PARAMETERS (or configuring the submodule after the initial
clone) be the solution for that?

The list of variables that is unset by clear_local_git_env is $(git
rev-parse --local-env-vars), currently

  GIT_ALTERNATE_OBJECT_DIRECTORIES
  GIT_CONFIG
  GIT_CONFIG_PARAMETERS
  GIT_OBJECT_DIRECTORY
  GIT_DIR
  GIT_WORK_TREE
  GIT_IMPLICIT_WORK_TREE
  GIT_GRAFT_FILE
  GIT_INDEX_FILE
  GIT_NO_REPLACE_OBJECTS
  GIT_PREFIX
