Wiki: relative links 404 -> absolute links OK

Links to the wiki in the current repo 404: they evaluate to "https://github.com/arekinath/uqrota/blob/master/arekinath/uqrota/wiki".
These links go to "https://github.com/arekinath/uqrota/wiki".

I'm not happy about the absolute paths involved and would welcome an alternative approach.

I haven't been able to find (through Google or experimentation) a way to use "the current repo URL" for the relative path, which in this case would be "github.com/arekinath/uqrota". When accessed from the web, the relative paths used before this commit start with "github.com/arekinath/uqrota/blob/master" -- don't know how to remove the branch from the link.

It should be a simple feature to link to specific wiki pages, but nothing's shown up in half an hour.
