hmm - so nvi does

        :set extended

which I hadn't noticed (manpage shows this):

       extended [off]
              Regular  expressions are extended (i.e.  egrep(1)-style) expres‐
              sions.

We could add something that allows the meta characters to change (calling
it "extended" doesn't seem right for various reasons).  Perhaps something
like

        :set meta-magic='<>'
