My preference is for option "a".  I'd rather have large files be an
exception and display the size with a "K" to indicate thousands of
sectors or whatever, than receive a string "**********".  While the
accuracy of the value would suffer, at least the number would be readable
by a human, would be readable by a program, and would not break existing
applications (until such time as a >4GB file shows up).
