Usage of file names that are reserved in Windows

[udosteinberg]

According to http://support.grouplogic.com/?p=1607 nul is a reserved file name in Windows (null device). Extracting a Seoul tree in Windows causes a lot of issues due to Seoul subdirectories being named "nul".

It's a shame that we have to work around such things, but we should rename that directory to something that does not cause conflicts.

True. Back in the day @vmmon and I never thought that anyone would want to do that...
