Fixed url generated by pull request/compare button ...

The `:` character was getting escaped leading to an ugly url. This is
different from the urls generated when editing the branches in a pull
request. In that case the url did not have `:` escaped.

Pullreqs in forks now use upstream master as origin ...

This implements #668.
