I managed to lose my todo-mode.el todo file. I don't really know how
this happened, I guess it was a combination of showing the todo file
while in the minibuffer and hitting C-g, but I noticed it too late, and
then could not reproduce.
In any case, I suspect that todo-mode.el itself deleted it, so I suggest
the following patch as a safety measure.
