bug#17350: [PATCH] grep: speed up for a case to repeat failure in DFA after success in kwset

[Paul Eggert]

Thanks, I installed that patch with minor reworking of the ChangeLog 
entry and am marking this as done.  By the way, a minor point -- 
nowadays we prefer single-quoting 'like this' rather than the old style 
`like this' -- the GNU coding standards changed recently in this regard.

I noticed a mostly-theoretical read buffer overrun in the patch, along 
with some other opportunities for simplification and tuning, and 
installed the attached fixup patch as well.
