Here's another one that ought to be easy to approve/reject.

The docs have been approved and we have decided that this should be 
mentioned in the NEWS if/when it goes in, but nobody has said anything 
about the code.

I don't think this one should be too much trouble because it does not 
change existing behaviour or do much out of keeping with other commands.

Is it OK?
