Hi All,

since some time I've been facing a small annoyance in the agenda, as 
when I move point in my weekly agenda to a day which is not the first 
one display and then hit "f" (`org-agenda-later') the agenda buffer is 
scrolled up, hiding the top of the buffer, even though there is no lack 
of space in the frame to fit the whole window.

This is not something that started after the most recent release, I had 
been observing this previously.  But I thought I might have missed some 
fix, and waited to see if the issue was still up after the release came. 
And it is.  I'd say since a couple of weeks, but it is easy to be 
tricked by memory in these cases, and it might be more.

I did some bisecting to be able to come up with a proper ECM, and it 
turned out to boil down to the interaction between my 
`scroll-conservatively' setting, and a combination in 
`org-agenda-custom-commands' of two agendas with different time spans 
(one weekly, the other daily).


An ECM to reproduce the issue is:

- Start 'emacs -Q'

- Do an initial setup:
  #+begin_src emacs-lisp
  (add-to-list 'load-path "~/.emacs.d/elpa/org-plus-contrib-20200921")
  ;; Latest Org weekly build (Org 9.4)

  (setq scroll-conservatively 10000)

  ;; Not essential to reproduce, but included just to emphasize there is 
  no lack
  ;; of space to trigger the scrolling.
  (setq org-agenda-window-setup 'only-window)

  (setq org-agenda-custom-commands
        '(("w" "Agenda"
           ((agenda ""
                    ((org-agenda-overriding-header "Agenda (Week)")))
            (agenda ""
                    ((org-agenda-overriding-header "Habits (Day)")
                     (org-agenda-span 'day)))))))
  #+end_src

Now, open this agenda with "M-x org-agenda RET w", move point to a day 
further down the first agenda block (e.g. today is Monday, go to 
Saturday).  Call `org-agenda-later' ("f") and observe the buffer was 
scrolled up so that the day of the week you were before is now made the 
first line of the buffer, and the previous ones are hidden.

As these kinds of scrolling settings interactions might be somewhat 
tricky to reproduce, I attach a couple of screenshots of the resulting 
situation before and after calling `org-agenda-later' as described in 
the ECM.

Best regards,
Gustavo.

Thank you for looking into this.

But I think the commit, though indeed avoids the reported undue 
scrolling, brings other undesired side effects.  Usually, 
`org-agenda-later' will carry over the current day of the week to the 
next week.  If we call it on Thursday, point will be placed on the same 
week day of the next week.

Just calling `(set-window-start nil 1)' there breaks this regularity. 
It is easy to generate a case where this happens.  Just squeeze the 
height of your window on a "populated" agenda, and choose a day for 
which that day next week won't fit in the window if position 1 is shown, 
and call it from there.

Perhaps doing so before the call to 
`org-agenda-find-same-or-today-or-agenda' would be a possibility? 
(untested)

Best,
Gustavo.

Hi Gustavo,

well, clearly my mind is dull right now - I pushed another better fix,
but please report any better solution if you have one.

Thanks!

Thank you.

No, not really, I just happened to spot an offending case of the 
previous commit.  Unfortunately, I don't have a silver bullet here.

Gustavo.
