Oops, I screwed up. I accidentally checked in Evan's tentative

changes for CancelAction with the test->tests checkin.  Undo this.

(I also screwed up my attempt to undo this silently in the RCS file --
I accidentally deleted revision 1.19 from the RCS file.
Fortunately, the log message for that revision said "Add 'nothing' to
the initial dictionary (its value is None)." and it changed only one
line, so that's no big deal.)
