--line-buffered typo

[chaz]

This is a typo, not particularly a bug.
I'm not sure if this is exclusive to the data for "man grep" running at my
university, but the manual text reads:

       --line-buffered
              Use line buffering, it can be a performance penality.


Clearly "penality" is a typo.

I hope this is helpful, it may be completely ungrounded, ie not the
"current" version of the man page, as I have very little knowledge of unix
development progress etc :)

Sincerely,
Chaz G
