RE: New multi-command facility displays in the wrong echo area.

Don't worry, it is now fixed.

The gain is explained in NEWS.27: When the minibuffer is active, echo-area 
messages are displayed at the end of the minibuffer instead of hiding the 
minibuffer by the echo area display.

For example, if you do C-x C-f, you see "Find file: ...".  If you now 
switch to another window and do C-s foo, you will see: "Find file: ... 
[I-search: foo]".

With earlier Emacsen, or with Emacs 27 and (setq set-message-function 
nil), you see instead: "I-search: foo" (that is, the "Find file: ..." is 
hidden).
