Real argument con is that you're making life easier on users of
GNU/Linux software whose authors ought to be taught how to write
portable code.
I think compatibility with GNU/Linux is a miserable reason for
bloating software on BSD - especially considering how NU the typical
GNU/Linux extensions are. However, this seems like a useful feature in
and of itself, and fits in well with the command it's being added to.
So adding it - and adding it to wc - seem like reasonable things. And
if we're going to add a feature to a command, making it compatible
with an existing implementation seems like a good idea.
