Two points:

- My personal init script still results in a frame that's 84 columns 
wide (according to frame-text-cols). There are no frame size settings in 
the configuration.

- There are still widths of the frame where evaluating the previously 
mentioned set-face-attribute form results in the frame shrinking 
repeatedly until it reaches one of the "stable" widths. Like in prevous 
test, the width 80 is stable. IOW, nothing seems to have changed WRT to 
the shrinking behavior.

Here are the contents of *foo* accompanying the 'emacs -Q' session where 
I first resize the frame to 90 columns (according to the wm) using the 
mouse, and then evaluate the set-face-attribute form 7 times until it 
reaches the width 80.

It does have a number of lines where "outer rest" is followed by values 
other than 0x0. It's only 0x0 at the end.
