Hmm... it would be good to find such a way, indeed, since the issue is
likely to show at other places where we'd want to use read-key.

Indeed, the scenarios where read-key is preferable to read-event in the
context of read-quoted-char are fairly hypothetical.

So, we should probably revert that for now, but adding a comment about
why we don't use read-key.
