Consistency of drive letter case in wxMSW

[ABX]

Hi!

I just added wxGenericDirCtrl control presentation to widgets sample with
additional showing of wxStandardPaths. I noticed when I set paths from
wxStandardPaths to wxGenericDirCtrl and read them back (Win XP) I have
different values and the mismatch is in case of drive letter. Suprisingly for
documents path it returns correct size of drive letter. I would prefer
consistency so user doesn't have to do own playing with the drive letter.
Should we have drive letters always upper, lower or whatever?
