Smaller, better, faster, donger

New features:
+ set buffer to 0 rather than wastefully having and flushing the buffer on
  each character
+ check for EOF so we can exit rather than just ^C or breaking a pipe
+ *++v rather than v[1] for more confusion
+ FILE instead of void pointer (can be reverted maybe)
+ most of the program inside for loop
+ has a single long line that respects 80 character limit
+ "setvbuf(f," and "fprintf(f," line up and that's pretty fucking cool

Additional notes:
+ if you don't pull i'll tell everyone you're a butt
