nothing earth-shaking changed.  it avoids regex for simple patterns which
places it roughly in the same speed bracket as gnu grep. (depends on how
many megabytes you're grepping if you'll notice a difference).  plus an
assortment of flags and corner cases which pop up when you make it system
default and lots of people start using it.
