Decided to rewrite module_clone to use connect_work_tree_and_git_dir as my microproject by suggestion of Stefan Bellar. https://public-inbox.org/git/CAGZ79kY+1E-wg0-uzGJmE+haOE+1WCmg0Eux7rWGtkU_aBDQ9g@xxxxxxxxxxxxxx/ It seems that connect_work_tree_and_git_dir needs to be slightly changed to deal with submodules. Because path to config file for submodules lies not directly in .git directory we need to know whether the path is submodule or not. Can I use submodule_from_path to determine this? I mean what if NULL result also indicates error sometimes? Another possible solution is to pass the flag indicating that path is submodule or not. But I think this solution is bad.
