The post-build step, IRC notification, allows 5 options of what to send to the channel.
Ideally, this should be customizable in a String.format() way.

But at least there should be an option to send a message containing the name of the build.

Therefore:

"Project windup-pr-builder build #1656: SUCCESS in 22 min: http://wonka.mw.lab.eng.bos.redhat.com/jenkins/job/windup-pr-builder/1656/"

would become

" Project windup-pr-builder build #1656: SUCCESS in 22 min: PR #924: Fixed some mistaked in the ...http://wonka.mw.lab.eng.bos.redhat.com/jenkins/job/windup-pr-builder/1656/"

The main motivation is the combination with Github plugin, which sets the name of a build to the name of the pull request. In this case, without this name, the message is not much useful.

Thanks for considering.
