Setlinebuf() has no effect on input streams.  I imagine setvbuf will
not set line-at-a-time reading on SysV either.  Think about it:  how
will you tell the system to read only up through a newline?

Using setbuf(stdin, (char *)NULL) will do the trick, but is terribly
inefficient.  I prefer my fseek-before-exit suggestion . . . .
