bug#24293: 25.1; Display bug: icomplete prompt not visible with icomplete-separator "\n"

[Michael Heerdegen]

Hello,

In emacs -Q, eval

  (setq icomplete-separator "\n")

and do

  M-x icomplete-mode <return>

Then, e.g.

  M-x m

The icomplete minibuffer prompt is invisible (bug).

But you see that it's "there" when you hit <left>.  And changing the
value of `resize-mini-windows' to nil makes the issue disappear - so I
think this is caused by a problem in the display code.


Thanks in advance,

Michael.
