They don't initialize (and use) their nongit variable.
Regards, Gábor
Always set *nongit_ok in setup_git_directory_gently()
setup_git_directory_gently() only modified the value of its *nongit_ok argument if we were not in a git repository. Now it will always set it to 0 when we are inside a repository.
Also remove now unnecessary initializations in the callers of this function.
