          Issue ID: 20392
           Summary: formattedRead: %*d and %d should read the same
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Severity: normal
          Priority: P1
         Component: phobos
          Assignee: nobody at puremagic.com

This throws an exception:

---
import std.format;

void main()
{
    string str = "foo bar buzz";
    string a, c;
    int b;
    formattedRead(str, "%s %d %s", &a, &b, &c);
}
---

This not:

---
import std.format;

void main()
{
    string str = "foo bar buzz";
    string a, c;
    formattedRead(str, "%s %*d %s", &a, &c);
}
---

The reason is, that %*d accepts an empty string as a number while %d doesn't.
