About the version at the footer of man page I can read:=20
"This page describes mv as found in the fileutils-4.0 package; other
versions may differ slightly."=20

You talk about 5.2.1 and 5.3.0 but don't know if you refer to fileutils
package or mv program, can you clarify this so I go to file a bug.
