[PATCH 0/1] MR10378: winemac: Avoid matching scan code 0 in GetKeyNameText.

[Marc-Aurel Zent (＠mzent)]

The `keyc2scan` array is populated with the `default_map`, which has the line

```
    { 0,                        0,              FALSE },    /* 0x34 unused */
```

An application requesting scan code 0 in `GetKeyNameText`, then matches this in `if (thread_data->keyc2scan[keyc] == scan)` and the subsequent call to `UCKeyTranslate` succeeds (probably an apple bug), but doesn't update len or updates the buffer in any way. So the random stack content of the caller is just returned.
