 I *vaguely* remember that in some particular test, perhaps on a very big
file, the unpatched grep was disgustingly slow in a UTF-8 locale, and that
patch seemed to fix it.  I also remember that fmbtest never used to work.
At one point there was some hackery upstream to get rid of failure reports
on tests that weren't expected to work at the moment.

 Unfortunately, my subscription to bug-grep was one of the things that
went when I lsot access to my old nthell mail, and I didn't notice.

 When I first saw this thread, I remembered nothing about it until Bruce
pointed out the patch had my name!

 Added to my ToDo list.

After tragedy, and farce, "OMG poneys!"
