From: "Gustavo L. de M. Chaves" <gnustavo@xxxxxxxx>
Routine _cmd_exec invokes _setup_git_cmd_env inside the child process
before invoking an external git command to set up the environment
variables GIT_DIR and GIT_WORK_TREE and, also, to chdir to the
repository. But _cmd_exec is only used on Unix. On Windows, it's not
used and the main code path is in _command_common_pipe, which didn't
prepare the environment like _cmd_exec.
Without this environment preparation some git commands, such as "git
clone", don't work.
We can't use _setup_git_cmd_env in this case because we don't use a
forking open like _cmd_exec does and don't get a chance to make such
preparations on the child process.
So, the preparation is done on _command_common_pipe by setting up
localized environment variables and by chdir temporarily just before
invoking the external command.
