When $GIT_DIR was not set and the repository is found as a .git
directory $GIT_DIR will be the full path to the .git directory when
calling git_config(). git_config() calls git_path() which calls
get_git_dir() which calls getenv("GIT_DIR").
I'm not sure this is defined behaviour at all:
char *foo = getenv("FOO");
unsetenv("FOO");
Does foo still point to the old content of the FOO environment
variable? If it does get_git_dir() will always return the full path
to the repository directory.
I can think of two ways to solve this (in case this is a problem):
1. Add a function to environment.c which will cause setup_git_env to
be called again (either directly or by setting all the pointers to
NULL again).
2. Use git_config_from_file() instead of git_config(). This will
probably duplicate code from git_config().
