    MoinMoin - BlurpSearch Macro

    just a modified FullSearch.

    [[BlurpSearch(term, prefix)]]
        A category serach, but only for pages beginning with prefix.
        If a ##BLURP pragma is on the page, it's contents are displayed
        after the match.
        The page links are shortened by the given prefix.
        The Category is only matched if exactly after a '----' line!
