The lines are way too long in this commit message. 72-chars except in cases
where there is no word breaks in the text.

id:1414101891-10714-1-git-send-email-imain at stemwinder.org has also one 
75-character line (and talks about 'This patch ...' which could be changed
too (but is tolerated if not)).
