For the comments we have lots of links, such as [se][se] and [ubuntu.se][ubuntu.se].
I thought it would be helpful to haveHere is a [launchpad] linklist of requested redirects, so we can easily direct users to it - i.e. the bug report site - https://launchpad.net/
So from me and the comments:
Detect the string[launchpad] goes to ppahttps://launchpad.net/ubuntu and make it into a link, likeshows as Launchpad
http[launchpad#bugnum] goes to https://bugs.launchpad.net/bugs/bugnum. So ppa:peterlevi/ppa would turn into ppa:peterlevi/ppa. and shows as (Wilf's comment)Bug #bugnum
