4.2bsd eof flag in stdio

     EOT  (Control-D) may be used to generate an end of file from
          a terminal.  When an EOT is received, all the charac-
          ters waiting to be read are immediately passed to the
          program, without waiting for a new-line, and the EOT is
          discarded.  Thus if there are no characters waiting,
          which is to say the EOT occurred at the beginning of a
          line, zero characters will be passed back, and this is
          the standard end-of-file indication.

\this is in the system manual; \i'd suggest both you
and \berkeley look it up (in a v7 manual if necessary).
fread() was \n\o\t designed for terminal \i/\o.
