Leading or trailing white space characters in file names

[Roland Melkert]

On a somewhat related, but separate note, I think that we should disallow white space before the 0 on the first line of an LDraw file, because the "0 " at the beginning of the file can be used as something of a magic number for the LDraw file type.

I'm not sure I completely understand what you mean here, but isn't this a 'header issue' instead of a 'file format' issue?
