OK, let's resurrect the issue when more people are actively
interested in having the right mechanism to propagate errors up in
the callchain.  I just re-checked the callers of copy_fd and I agree
that this will not affect existing callers (including the one in
hold_lock_file_for_append() called by add_to_alternates_file() that
passes LOCK_DIE_ON_ERROR), so I am inclined to drop the patch for
now.
