Subject: 24.3; minibuffer resizes when message contains bold or italic text
Date: Fri, 31 May 2013 16:28:53 +0200

[Message part 1 (text/plain, inline)]

When a message contains bold or italic text, the minibuffer is resized
incorrectly. E.g.  consider the following two commands:

(defun x () (interactive)
  (let ((message "Hello World"))
    (put-text-property 0 5 'face 'bold message)
    (message message)))

(defun y () (interactive)
  (let ((message "Hello World"))
    (put-text-property 0 5 'face '(:foreground "blue") message)
    (message message)))

On "M-x x" the minibuffer will look as if the message contained a
trailing newline. On "M-x y" the minibuffer will display correctly.

eldoc's tips become distracting as this causes random flickering of the
minibuffer while moving the cursor through code.

The problem is reproducible at least in all emacs-24.x-bin-i386.zip
releases on http://ftp.gnu.org/gnu/emacs/windows/

The problem is not reproducible in the Cygwin version
GNU Emacs 24.3.1 (i686-pc-cygwin, GTK+ Version 3.4.4) of 2013-04-26

Why do you think it is incorrect?

It doesn't happen to me with 24.3, but that's on XP, while you are on
Windows 7.  So I'm quite sure it's a font and/or shaping engine thing.
Somehow, on your system the font tells Emacs that its height is more
than you think it should be.  Emacs has no alternative but to comply.

(I'm going through old bug reports that unfortunately weren't resolved
at the time.)

I'm unable to reproduce this problem in Emacs 29 -- are you still seeing
this issue in recent Emacs versions?

No, I can't reproduce it now either.

Thanks for checking; I'm closing this bug report, then.

It can legitimately happen if the bold font is either slightly higher
that the default font, or the line displayed by eldoc is longer than a
single screen line.

This is not a bug, even if it still can be reproduced.

However, the OP didn't say what was on line 902 of abbrev.el in that
version of Emacs, so it is impossible to find out what actually
happened.
