Bug description:
[Impact]
Emacs users can't access the help screen for the ediff tool.
[Test case]
(For non emacsy people)
Run emacs in a graphical environment
Menu option: Tools->Compare->Two Buffers
ENTER and ENTER to the two questions prompted
A new window, 'Ediff', opens and contains the text "Type ? for help"
In the 'Ediff' window, type the character '?', This is supposed to display
helpful info on the ediff commands
If broken:
Ediff window will expand, then shrink horizontally to one character wide
Grabbing the frame and resizing will cause the shrinking behavior to repeat
If fixed:
Ediff window will expand and show the contents of the help
[Regression potential]
It could be that some other graphical environment relies on the bug being
present, working around it in a way that if it's not present anymore, the
window resizing will break there. The current patch is tested for Unity and
Cinnamon, and has been taken from the fix already applied upstream.
[Original description]
Unlike previously reported bug #941790, this bug involves a horizontal
shrinkage to one column wide (multiple rows), and is still present in GNU Emacs
23.3.1. Resizing the window isn't a work-around, as the window immediately
shrinks again. The behavior is observed as follows:
Run ediff-buffers
A new window, 'Ediff', opens and contains the text "Type ? for hlep"
In the 'Ediff' window, type the character '?', This is supposed to display
helpful info on the ediff commands
Ediff window will expand, then shrink horizontally to one character wide
Grabbing the frame and reszing will cause the shrinking behavior to repeat
Releveant packages / versions:
Ubuntu 12.04.1 LTS
GNU Emacs 23.3.1
Unity 5.16.0-0ubuntu1
