I just encountered a bad effect that I assume is caused by this change,
since it didn't happen before: when I type `h'
(gnus-summary-select-article-buffer) in the Gnus Summary buffer, this
splits the window and selects the Article buffer as it's supposed to,
but in the Summary buffer point simultaneously moves to point-min; it's
supposed to stay put.  The same thing happens when I have split windows
with the Summary and Article buffer and in the former type C-x o
(other-window).  I haven't been able to reproduce this with other
buffers, but only with Gnus Summary.  Still no abort, but this effect
means the fix -- if it is one -- at least needs further tuning.
