Sorry, but ...

At the beginning of repo_config_values() in the patch, there is a
check to ensure that repo->initialized is true and otherwise you get
an error.  But the initialization is already done in the early part
of initialize_repository() as quoted above.  So I do not see what
difference it would make if we rewrote the last line as

	repo_config_values_init(&repo->config_values_private_);

I am confused.
