Relative links

[acjbizar]

Absolute links (like http://example.com/) and anchor links (like #example) appear to be working fine, but of course we also have something called relative links. These cause a bit of trouble with at least the [button] shortcodes. Links like example, /example, ./example, and ../example are prefixed with http:// for some reason, rendering them invalid, while just leaving them alone would be fine.
