The rename is ok.  Even though it's an internal command and rarely used 
I think the renaming should be mentioned in NEWS for future reference.

I think I added it originally - if I was doing this again, I would add a 
test even though it's internal.  However, I don't insist on you adding a 
test to merge it.
