Nice detective work! Thanks for sharing it.

Alex or one of the other doc-oriented people: is it worth opening a bug
about these undocumented features? Can we add this snipper Xiangyun has
written to the wiki or somewhere else? Or is it the case that these
undocumented commands are so super secret that you don't want any
documentation about them to be part of the product?
