unsigned char *, to avoid some technical violations of the C
standard, and to avoid the need for casts. I guess the
unsigned char * was probably there for improved performance
with ancient compilers, but the code wasn't using the
unsignedness any more.

fix any bugs since the buffer size is small, but it makes
the code a bit clearer.

been reading one byte at a time. POSIX currently doesn't
require this, but it's easy to do and some software relies on it.

written; this typo was harmless before, but is no longer harmless with
the above change in effect.
