That is basically what my command does (with the difference that I don't
just check if (mark) is non-nil but also if (use-region-p) is non-nil),
just not part of kill-region.  I don't know if this is too invasive, if
users are used to this error being signalled.  Perhaps it can be
protected by a user option?
