Comment (by nomeata):

 Thanks for the patch!

 It is common to comment when you change the status of the ticket,
 something like “I worked on this and here is the result. From my point of
 view, it is good to go. Can someone review and push it” and possibly more
 (e.g. whether it was hard or easy, whether you like the result or not). A
 simple status change may be overlooked.

 Besides that, the patch (which has a sufficient comment and a test case)
 looks good from my pov. Unless someone complains I’ll push it soon.
