When an absolute link doesn't have "WebHome" it becomes relative blocking users from linking pages on other page trees

When an absolute link doesn't have "WebHome" it becomes relative.

If you have a page /bin/view/PageA/PageB and inside it you create a link:

[[Main.WebHome]] or [[doc:Main.WebHome]]

It will be handled as an absolute link and it will point to /bin/view/Main

But if you remove .WebHome:

[[Main]] or [[doc:Main]]

It will point to bin/view/PageA/PageB/Main

This essentially means that links without WebHome can never be absolute (and therefore you are forced to use WebHome if you want to link to a page that is not a child of the current page)
