Turn it around.  Is there some reason we would _want_
to design the right column so it behaves differently
from other columns?  Is that a feature that you find
useful?  If there were a special cost to doing that,
would you go to the trouble to add that to the design?

Which "feature" is more useful?  The one you can't
see yourself wanting or the one I proposed: nothing
special about the right column?

Other things being equal (and they may not be - please
explain), why wouldn't we want the columns treated the
same?

Oh, your window is narrow enough that it effectively
narrows the right column.  Fair enough.  Is that your
solution: resize the window (or perhaps the frame, if
one-window) instead of just the right column?  Sure,
that's one workaround.

Or maybe you'll push the frame off the right side of
your screen, to, in effect, truncate the right column.
That's another.

But if you have a feature that automatically fits
windows or frames to buffer content...  (My case.)

Is this the end of the world?  No.  I consider it a
minor bug.  You have a right to consider it a feature
or not a bug at all.
