1 Need to improve [[globlist]]s, adding more powerful boolean expressions.
2 The current behavior is to check for negated expressions, and not match if
3 there are any, then check for normal expressions and match if any match,
4 This fails if you want to do something like match only pages with tag foo
5 that are under directory bar. I think we need parens for grouping, and
6 probably also boolean OR.
