Unlang and !*

[Brian Candler]

Just a minor point: unlang accepts the syntax

    if (Foo !* "any") {
        ...
    }

but it doesn't behave in the same way as !* in a 'users' file.

=* and !* are not documented as being available as comparison operators in
unlang (only as filtering operators), and there's no particular need for
them since you can instead write

    if (!Foo) {
        ...
    }

But I think it would be better if it rejected them outright as a syntax
error if you tried to use them.  It has caused some local confusion
recently.

Regards,

Brian.
