winedump: Remove dead code (Coverity) (resend)

[Andrew Talbot]

What is wrong with this patch (for CID-41), please? The relevant code section
is:

    if (effective_sig == SIG_UNKNOWN)
    {
	printf("Can't get a recognized file signature, aborting\n");
	ret = 0;
    }
    else if (wanted_sig == SIG_UNKNOWN || wanted_sig == effective_sig)
    {
	switch (effective_sig)
	{
	case SIG_UNKNOWN: /* shouldn't happen... */
	    ret = 0; break;

I thought being in the "else" of the outer "if" ruled out the possibility of
the "case SIG_UNKNOWN" being true.

Thanks,

-- Andy.
