a few very minor cleanups

src/cmd/INIT/mamake.c:
- Fix usage message.

src/lib/libast/include/stak.h:
- Since this header was restored for backward compat purposes only,
  typecast the four void* functions back to their old char* types.
  (re: a45a0eb)

src/lib/libast/man/sfio.3:
- Fix typo causing formatting error. (re: 086d504)
