When writing post-command-hook code, you have to be check whether you're
in the context you want to be (for instance, in the minubuffer or not).
I think it's always been this way, but these day we use the
read-from-minibuffer a lot more than we used to -- so y-or-n-p didn't
use to have this issue, but it does now.
But I think things are working as designed here, basically, so I'm
closing this bug report.
