Oh, neat. :P
(Don't see how I overlooked that)
As for line counting, it would be very possible for each -param that is givne to /fseek, but using /fseek for position would arise the problem in counting $crlf.
He is using C, It wouldn't be too hard for him to have an integer counting \r\n up to the point the file pointer is at, even though /fseek -w may *jump* to a certain place in the file, the entire file is still being read, each line. Not with moving position though which does create a problem ;/
I would like to see this feature, but now that I really think about it, the C code might not allow this to happen too easily.
