This is because Most pages are sub-pages of views, as in:

  http://foo.com/aContact/info/index..html
 
To refer to the edit view, as a relative link, we need:

  ../edit/index.html

Normally, relative links are relative to a view.

It's the way they are suppposed to be.

Note that an alternative would be to use absolute URLs where the
views generate the absolute URLs for the content.
