Ah, yes, I understand.

Well, you could do this:

if (S_ISREG(st.st_mode) &&
		lseek(input_fd, 0, SEEK_CUR) - input_len != st.st_size)
	die("...");

Of course, this suggests that a file containing a pack must not have _anything_ after the pack. But AFAIR the reading part chokes on "garbage after pack" anyway.
