[O] org-map-entries moves point

[Florian Beck]

When I call org-map-entries with scope set to 'tree, the current heading 
gets realigned to the top.

Behold:

(org-map-entries (lambda ()
                   ;; do something or even nothing
                   ) nil 'tree)

I think the culprit is the call to `org-agenda-prepare-buffers', or 
rather commit fe3379bda6ca23474639b114592958bf14431c88, which replaces 
save-excursion with save-window-excursion.

What's interesting: This does NOT restore the window configuration. When 
I replace save-window-excursion with save-excursion the window 
configuration is restored again.

I'm not sure *why* this happens.
