[PATCH 0/1] MR8464: ntdll: Collapse paths in get_unix_full_path.

[William Horvath (＠whrvt)]

Before the commit in question, both of these paths would be parsed as valid (with e.g. FindFirstFile):
```
Z:\tmp\*
/tmp//*
```

After the commit, only the DOS path is accepted, while the Unix path returns ERROR_INVALID_NAME.
