  Unescape D\: in f_dir - Fix CVE-2014-10401 for Windows

The DNS returns f_dir as C\\:\\\\Foo\\\\DBI\\\\test_output_12345

for my $dl ("", "c", "C") {
  for my $c ("", ":", "\:", "\\:", "\\\:", "\\\\:") {
    for my $f ("/", map { "\\" x $_ } 0..5) {
      my $d = $dl.$c.$f or next;
      printf "%2s %5s %-8s %-15s %s\n", $dl, $c, $f, $d, -d $d ? "Yes" : "No";
      }
    }
  }

Shows that -d accepts optional drive-letter-colon (drive letter is case
insensitive too). Doubles \ in path are no problem, but escaped : will
not be valid
