In the same place where 'C-x 8 RET' (insert-char) does this:
it has no "*" in the interactive spec, and allows using it
in read-only buffers to browse a list of character completions
with TAB, but exiting the minibuffer with RET signals the error
"Buffer is read-only" somewhere in the 'insert' functions.
