It would be, if it wasn't for the fact that we may know the filesize
when seeking is not possible (and demuxers can thus not deduce the
filesize by "seeking" to the end). I still think returning success on
seek only for end,-1 and back to the current position is too much of a
hack and I'm pretty sure you would agree (please say yes here :-) ).

I don't mind if file_size is not available for a while (until whenever
is the next time that ABI is broken) on such streams, but it should be,
eventually. Adding file_size really is the right thing to do, imo.
