Okay:

        if (S_ISDIR(st.st_mode))
                st.st_mode |= S_ISGID | S_IXGRP;

Yes.

How about an "else" in front of the "if"? Like so:

                if (mkdir(path, 0777) < 0)
                        if (errno != EEXIST) {
                                *pos = '/';
                                return -1;
                        }
                else if (shared_repository && make_group_writable(path)) {
                        *pos = '/';
                        return -2;
                }

You want me to resend the patch?
