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?

Anyway, personally, I gave up with the SCO Unix vi and use the SCO
Xenix vi instead.  Doing that does pose problems, like % substitution
doesn't work from the :! mode (top bit gets set), but that's a lot
less hassle than broken regular expressions.

The Xenix vi is directly descended from the BSD (no AT&T parentage other
than the original ed code) "ver" says 3.7 6/10/83.  Putting the
date in is so much more informative than just "SVR3.1".
