This complicate the code and force external apps to handle this, see

Sorry, but it is:

Selecting foo → bar in a list results in foo^@bar being entered into the
minibuffer, not with the query-replace interface but when handling the
history list from somewhere else.

It doesn't see above.

The patch change nothing and allow same customization as before.

I wrote this patch because I think it makes the code better, allow
easier customization and fix issue described above.

I understand if you want to keep the code as it is to be sure nothing
wrong is introduced in a code that is already "working".

Thanks.
