Re: say how grep can find non-ascii

[Dan Jacobson]

Anyways, I can't believe the mighty grep got along all these, what, 40
years, without a way to say 'find me a null' or 'hex 04' without being
forced to feed it raw characters. OK http://en.wikipedia.org/wiki/Grep
says there are many versions, so no wonder GNU grep doesn't act like a
40 year-old. Anyway, raw characters would still be OK: but then mainly
say this is indeed needed on the man page.
