This adds decl-after-statement.  As referencing argv[argc] is not a
crime (you will grab a NULL), how about doing it this way to see if
the value is a NULL, instead of comparing the index and argc?

        const char *gitdir;
        if (!argv[++i])
                die("--resolve-git-dir requires an argument");
        gitdir = resolve_gitdir(argv[i]);
        if (!gitdir)
                die("not a gitdir '%s'", argv[i]);

Same comment may apply to other hunks.
