I've been informed that `C-g' is bound in the original buffer to an appropriate abort function.

Currently C-x 1 has the same issue as Esc*3, but I assume that is another bug. ;-)
True. It can, however, be made DTRT with Esc*3 quite easily. And with winner-undo, too. (Basically, everything that got an appropriate hook.)
It could theoretically be made to work for `C-x 1', too -- that is every time the *Fuzzy Completions* buffer becomes non-human viewable -- but I'm not sure it's worth the trouble.
