Unbelievable that I forgot that recently I already implemented
(setq-local command-error-function 'minibuffer-error-function)
for the minibuffer :-)
So like we already have 'set-message-function' that can be set to
'set-minibuffer-message', the corresponding pair of existing error-related
functions are 'command-error-function' and 'minibuffer-error-function'.
This there is nothing to do more here?
