scripts/get_maintainer.pl --self-test=links has a reachability test
using wget.

Perhaps a script like that could be used for http:// vs https://

	## Link reachability
	} elsif (($type eq "W" || $type eq "Q" || $type eq "B") &&
		 $value =~ /^https?:/ &&
		 ($self_test eq "" || $self_test =~ /\blinks\b/)) {

	    my $isbad = 0;
	    if (grep(m@^\Q$value\E$@, @bad_links)) {
	        $isbad = 1;
	    } else {
		my $output = `wget --spider -q --no-check-certificate --timeout 10 --tries 1 $value`;
		if ($? == 0) {
		    push(@good_links, $value);
		} else {
		    push(@bad_links, $value);
		    $isbad = 1;
		}
	    }
	    if ($isbad) {
	        print("$x->{file}:$x->{linenr}: warning: possible bad link\t$x->{line}\n");
	    }
