I've just updated my working tree of Emacs from trunk and
found that you have already committed a new patch.  So, I
tried it and confirmed that it worked well.  Thank you!!

My understanding of rmail-redisplay-summary is that when it
is non-nil, rmail-summary-buffer is forced to be shown.  For
instance, when rmail-summary-buffer is buried and I change
the current message in RMAIL buffer by typing p,
rmail-summary-buffer pops up.  As I don't want that
behavior, I haven't customized rmail-redisplay-summary to t.

What I want is that rmail-summary-buffer is shown in some
window of the specified height when I type h in RMAIL
buffer.
