Thankyou for looking into it Tye. Some of that is still over my head (what's new:), but it's interesting to see that this is one of those cases where simplifying the code may improve it's flexibility. Good luck with the patch. I have encountered several situations in which this 'fix' would have simplified my code when writing filters for binary files.

If I ever work out how to get MinGW to build the sources, I guess I could add the patch to my own copy. First things first though:)
