Subject: Bad 'grep' behaviour in -CURRENT, faulty binary detection?

I just happened to notice this today. For some reason 'grep' seems to
think that 'set' output is binary, not text. Seems that GNU grep 2.3 is
a little too sensitive to text/binary detection. This only seems to
affect -CURRENT because -STABLE runs GNU grep 2.0.  (This was committed
October 28th). 

Now, I haven't looked at exactly how the code works, but it evidentally
looks at the beginning of the file to detect it. You can use -a to
override this of course. I'm not sending a PR or anything since this is
'arguable' on whether or not it's a bug or just being over sensitive.

Here is an example of the output:
