| Regular expressions in SCO Unix vi seem to be severely broken, I *think*
| it's closure of a character class that does it.  "ver" on SCO Unix says
| SVR3.1, does anyone know if the base port for that has such problems?
|

+---------------

I beg your pardon?  The SVR3.1 at work has "vi", and it does *not* have any
regexp bugs --- I've had to use it often enough that I would most definitely
have crashed into them by now.  (I prefer Emacs, but I can't install it on
every machine I work on --- client sites, for example.)

In any case, don't be so quick to nail AT&T to the cross for something that
showed up in an SCO product.  It might have been AT&T, or SCO, or SCO might
have gotten it from someone else (did Interactive have anything to do with the
initial 386 SVR3.1 port?).

I *do* have to wonder why a "3.2" Unix comes with a 3.1 vi, though....
