The [[RecentChanges]] page is broken (doesn't show any history at all) when used with an empty svnpath in the ikiwiki.setup file.

Say you have the following configuration:

    rcs => "svn",
    svnrepo => "ssh+svn://foo.bar.com/wiki",
    svnpath => "",

In the above, $svnpath need to be either empty or "/" - both trigger the 'next unless' check in IkiWiki/Rcs/svn.pm:rcs_recentchanges() as shown in the patch below, thus causing all files to be ignored for [[RecentChanges]].

I can not see why this check is needed in the first place, so here's a patch for removing it :)
