stuck undo after cc-mode fill |

1. Start emacs with emacs -q --no-site-file
2. Blank the *scratch* buffer, put it in c-mode
3. type asdf
4. C-/ will undo it
5. type asdf again
6. type M-q
7. C-/ does nothing no matter how many times it's pressed
8. make another change
9. now both changes can be undone
I can reproduce this behavior on the latest CVS. Commenting out the undo
bit of c-mask-paragraph fixes the problem. It seems like undo choked on
nil, position, nil in the undo list.

I can reproduce this in 22.3, but not in 23.1 onwards, so it looks like
it was fixed.
