Subject: sort.cc Bug correction

The following changes have to be made in the sample-Program sort.cc
to compile without warnings (changes 1-3: unsigned char -> char)
and not to crash with Segmentation violation when no filename argument
is given (i.e. standard input is to be sorted).
(at least this is true on my AT 486/33 clone).
It's not that much important, but it is the first time I used the compiler
and it was the first program I tried to compile and the result was a crash,
which was a bit disencouraging.
