[patch] correct file(1) printed usage

[Sébastien Marie]

Hi,

I would report (and correct) an invalid usage statement of file(1).

$ file
usage: file [-bchiLsW] [file ...]

$ man file | grep -A1 'SY'
SYNOPSIS
     file [-bchiLsW] file ...

As at least one argument is mandatory, removing the [] would make sens.

Thanks.
