Links in child modules are wrong

Links in child modules, as specified in that child site's site.xml, point to the wrong location. Where they point wrong varies if you're deploying to a file:/// location or a scp:// location, but regardless they're still wrong.
I've attached a zip file of the results of these steps, but here are the steps to re-create:

mvn archetype:create -DgroupId=com.test -DartifactId=parent-site -DarchetypeArtifactId=maven-archetype-site-simple
Change the <site><url> to file://c:/temp/website
Add a <url> of file:///c/temp/website
add <menu ref="modules" /><menu ref="reports" /> to site.xml
Change the commented out line to read: <item name="Parent Xdoc Example" href="xdoc.html"/>
create an empty file parent-site/src/site/apt/xdoc.apt

mvn archetype:create -DgroupId=com.test -DartifactId=child-site -DarchetypeArtifactId=maven-archetype-site-simple
Change the site URL to file:///c:/temp/website/child-site
in parent-site/child-site/src/site/site.xml, uncomment the Xdoc Example and set the inherit="top" on the menu.
add <item name="Foo Example" href="foo.html"/>
create an empty file parent-site/child-site/src/site/apt/xdoc.apt
create an empty file parent-site/child-site/src/site/apt/foo.apt
mvn site site:deploy

Navigate to the child website in a browser
Notice: "Parent Xdoc Example" link in child website is wrong. It points to the child's xdoc file.
Notice: the child's "Xdoc Example" and Foo Example don't point to their respective files. They point to the directory child-site.

Further: Replacing the file:/// references with scp://server/path result in even further breakage of the same links. Now foo.html points to "../../foo.html" instead of "foo.html"
