This is a simple plugin to convert all site-relative links to page-relative links (converts /foo into ../../../foo or similar). It works as a postprocessing filter, allowing it to work on mdwn, wiki, html, rst and any other format that produces html. The code is available here:

    #!/usr/bin/perl

    package IkiWiki::Plugin::siterel2pagerel;

    use warnings;
    use strict;
    use IkiWiki 2.00;

    sub import {
            hook(type => "sanitize", id => "siterel2pagerel", call => \&siterel2pagerel);
    }

    sub siterel2pagerel (@) {
            my %params=@_;
            my $baseurl=IkiWiki::baseurl($params{page});
            my $content=$params{content};
            $content=~s/(<a(?:\s+(?:class|id)\s*="?\w+"?)?)\s+href=\s*"\/([^"]*)"/$1 href="$baseurl$2"/mig;
            $content=~s/(<img(?:\s+(?:class|id|width|height)\s*="?\w+"?)*)\s+src=\s*"\/([^"]*)"/$1 src="$baseurl$2"/mig;
            # FIXME: do <script and everything else that can have URLs in it
            return $content;
    }
