## Message

```
Fix fmt.zig handling of slices of slices

Discovered while calling testing.expectError on an error union with payload [][]const u8. Even though the payload was not going to be printed, the current format handling caused a compile error anyway because it couldn't be casted to []const u8. The new handling treats a []u8 as a string but otherwise treats the slice as a pointer.
```
