bug#9449: Bug report on 'wc' : characters count adds one character

[Laurent TARRISSE]

Hi,

Documentation on 'wc' says:
----------------------------------------------
wc -m, --chars
              print the character counts

----------------------------------------------

But here follows the output I get:

>echo toto | wc --chars
5
>echo five | wc --chars
5
>echo four | wc --chars
5
>echo f  | wc --chars
2
>echo "" | wc --chars
1

Why does 'wc' add one character ?

Thanks.
