Some folders/filenames are not displayed correctly on FAT32 volumes under grub4dos

This seems to be a 'feature' of grub4dos from at least 2009 onwards (and probably from the year dot!).
You may have noticed that grub4dos does not always list all file names and folder names in the correct case.

e.g. under Windows or linux, we can list these files on a FAT32 volume:

AA
bb
Cc
CCC.txt
ddd.TXT
ANTIVIRUS
ANTIVIRU

but the same files are listed by grub4dos in the console as:

aa
bb
Cc
ccc.txt
ddd.txt
ANTIVIRUS
antiviru

I have reported the bug to chenall and suggested a fix which I have tested and it seems to work.
