Yay, a docs arms race! :-) I'll raise you one:

This document, "FAT32 File System Specification", states as the only requirement that "the short name is automatically generated from the long name in such a way that it does not collide with an existing short name".

That document is a description how Windows 98 creates short filenames, not a fat32 filesystem specification.

Interesting. We've done it this way since november and you are the first to even notice it.

Only if you can convince me that I am actually violating the specification and not just doing it differently than the win98 code.
