Well, the list is very short.  Really the only candidate is ^C -- there I
can imagine the user exclaiming: "But I didn't do anything!"  Calling
up help (^G) feels like a big interruption and the user probably expects
the chain of ^Ks to be broken then.  And M-- and M-= actually do move
the cursor, so they should and do break the chain.

That won't work.  All cursor movements are viewok.
