>Description:
        The new /usr/bin/vi doesn't support the matchchars option.

        I have marked this "critical" because it's a regression
        in functionality that used to work.

>How-To-Repeat:
        Run the new vi, in a context where $HOME/.exrc contains a
        command like

            se matchchars=''""(){}[]

        Observe these error messages:

            set: no matchchars option: 'set all' gives all option values
            Ex command failed: pending commands discarded

        Alternatively, start vi and type

            :se matchchars=''""(){}[]

>Fix:
        1. Add the matchchars logic to the new nvi.

        2. Check whether there are any other options present in old nvi
           but not new nvi, and add them too.
