tail & head manpage detail

[Herculano de Lima Einloft Neto]

Hello,

Both the tail and head manpages have something like:

  -n number
              The location is number lines.

It should be:

  -n NUM, -NUM
              The location is NUM lines.

The information that you don't need the 'n ' is missing.

Best,
