I don't think the literal char code used in the file system
for marking EOF is even relevant here. On the compilers and
systems I've checked, EOF gets #defined to be (-1) in stdio.h
This is merely the return code that getchar returns when it
encounters an end of file condition and has nothing to do with
how the file system determines where that end of file is.
