Some question regarding tail and option "-c"

[Robert Milasan]

Hello, I think I found an issue, but not sure if it's a bug or
feature :)

When using option "-c" from tail there are 3 ways, two working and one
not:

1. cat /etc/passwd|tail -c 10 (doesn't work)
2. cat /etc/passwd|tail -c -10 (works)
3. tail -c 10 /etc/passwd (works)

Why does the option 2 and 3 work, but the first one doesn't?
