Had a missing `nil`.

It looks fairly safe, but is it a regression in Emacs-29 or was it
already there in Emacs-28?  If it's not a regression in Emacs-29, I'd
keep it in `master`.

`read-char-from-minibuffer-insert-char` is a function which just inserts
a char and then exits the minibuffer.  With my patch,
`self-insert-command` should work as well for that.
