If you're determined to 'tweak' RedCloth this seems to work:

require 'redcloth'

class RedCloth
def inline_textile_link( text )
text.gsub!( LINK_RE ) do |m|
pre,atts,text,title,url,slash,post = $~[1..7]

url, url_title = check_refs( url )
title ||= url_title

atts = pba( atts )
atts = " href=\"#{ url }#{ slash }\"#{ atts }"
atts << " title=\"#{ title }\"" if title
atts = shelve( atts ) if atts

"#{ pre }<a#{ atts } target=\"_blank\">#{ text }</a>#{ post }"
end
end
end

puts RedCloth.new('Read "the friendly
manual":http://redcloth.rubyforge...).to_html

However, are you sure it's necessary?

rc = RedCloth.new('You "really
should...":http://c2.com/cgi/wiki?KeepItSimpleS...)
puts rc.to_html.gsub(/<a([^>]*)>/,'<a\1 target="_blank">')

Cheers,
