I agree with (a), but not with (b). I think separating the computation
of the position and the diagnosis makes it clearer.
I reworked the code a bit, the diagnosis part now looks like
if (dash_dash_pos == 0)
return 1; /* case (2) */
else if (dash_dash_pos == 1)
has_dash_dash = 1; /* case (3) or (1) */
else if (dash_dash_pos >= 2)
die(_("only one reference expected, %d given."), dash_dash_pos);

OK, I buy your version. Thanks,
