[PATCH v2] CMD: Always keep drive letter uppercase.

[Gareth Poole]

Windows and DOS before it has always kept the drive letter in uppercase at the command line, regardless of what input it is given. Since drive letters are case-insensitive this should not affect path resolution, but it is more consistent with both the behaviour of Windows, and the behaviour that Wine CMD already displays with directory names, which it shows in their canonical case.
