In minibuf-eldef-setup-minibuffer there is this form
(add-hook 'post-command-hook #'minibuf-eldef-update-minibuffer nil t)
I think this is not correct. The APPEND parameter of add-hook should be
t so all changes made to the minibuffer content by previous functions in
post-command-hook are taken into account by
minibuf-eldef-update-minibuffer.
Here is a patch for the trunk.

That sounds reasonable, but I'd be happier to know of a concrete example
where this was needed.

Christopher, do you have an example that demonstrates why this is needed?

IIRC, I played around with another prompt-simplifying form in
post-command-hook. I do not have the source code any more.
It is easy to come up with an artificial sample which demonstrates this
issue. Yet, even if minibuf-eldef-update-minibuffer is appended to
post-command-hook, does this change actually improve the situation? I
do not think so. It is not hard to come up with another sample which
requires the initial behaviour.
This issue is probably not a bug and does not matter to me any more.
Closing...
