[Bug 1059633] Re: Emacs 'Ediff' Window Shrinks Horizontally To One Column Wide

[Sebastien Bacher]

@Marga: that seems a fix worth a SRU for the LTS, there are quite some
hackers using emacs and several who found that bug report.

I will sponsor your precise diff, could you add the SRU infos to the
bug? (impact, test case, regression potential)?

Should we fix emacs23 in raring as well?

Bug 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
