Re: [PATCH 1/6] config.c: avoid git_path() in do_git_config_sequence()

Given that git_pathdup() does

	do_git_path(the_repository, NULL, pathname, fmt, args);

I am not sure what you mean by "tied to the current worktree"
above.  As do_git_path() uses strbuf_worktree_gitdir() that does

	if (!wt)
		strbuf_addstr(buf, repo->gitdir);

you meant s/current worktree/current repository/, perhaps?  In which
case I think the description makes sense to me.

Thanks.
