The choice to exclude parens from PmWiki urls by default is/was a
deliberate one -- it was decided that they're quite a bit more
useful when not treated as part of a url:

    [[(http://)google.com]]

    See my home page (http://www.pmwiki.org/index.php).

Note especially that in this last case we don't want the paren to be
treated as part of the url, even though it's a valid url character there.

However, as noted above, a site administrator is free to locally
configure $UrlExcludeChars to allow parens.

Another way to encode a paren in a url is to use %28 or %29, thus:
