Comment 1 for bug 404131

Only one part of this bug is actually a bug, imho: the link should only ever refer to the code vhost.

The URL rule already verifies that all numbers are never linked to a branch (there's a fix released bug about this). Also, if you look at your own bug comment, you'll see that lp:1234 links to the bug report.

There is no way we're going to check for the existence of the development focus. It would cause too many database queries. Note that the current behaviour of bug linking is to create a link to a bug regardless of its existence.
