Fix broken thunking of infix:<notandthen>
Fix broken thunking of infix:<notandthen>

`42 notandthen say "hi"` should not produce any output, but it does.

Fix by adding it to the list of ops in the actions for which thunk
is processed. This does not fix the `notandthen=` case, which will
be addressed in a later commit.
