Works and has tests. Committers, please push this along with "Fix some
compile warnings in Commands/Move" (part of patch750) and "Style and error
message clean up for patch733" (attached).
Oops, I forgot to push patch "Fix some compile warnings in Commands/Move".
I've pushed it now.
After discussion on IRC, I've consolidated all the previously mentioned
patches into a single ask-deps patch named: "Patch 733 dependencies"
