FRIGN 38066de8c2 Audit head(1) ...

1) Use (s)size_t in head().
2) BUGFIX: only check buf[len - 1] when len > 0, else there would
   be an overflow when getline returns 0 (which can happen) and a
   very potential segmentation fault.
3) fix error-messages.
4) update usage().
5) argv-argc-style.
6) clear up the main loop with if (newline).
7) add newline before return.
