Thanks for explanations.  I thought it is specific to
`delete-selection-mode` and `read-char-from-minibuffer`.
But since a combination of `pre-command-hook` and a recursive command
is a general problem, and OTOH `read-char-from-minibuffer` is already
safeguarded by the let-binding of `this-command`, so probably
`when (minibufferp)` could be removed from
`read-char-from-minibuffer-insert-other`.

Frankly speaking, I'm afraid of making such change at great depths ;-)
