tail +n does not work under Linux?

[Christophe LYON]

Hello,

I have just noticed that 'tail +n' does not seem to work under Linux.

For instance:
$ tail +3 .cshrc
tail: cannot open `+3' for reading: No such file or directory
==> .cshrc <==
[...]

I am using coreutils-7.2, and I have just reproduced the issue with 7.3, 
under Linux RHEL 3 and 4. Curiously, it works OK under Solaris 8.

... and tail -3 works.

Have I misunderstood the doc, or is it a bug?

Thanks and regards,

Christophe.
