Bug: Remote state change of repeating TODO fails with calendar open [7.8.03]

[Thomas Morgan <tlm@ziiuu.com>]

Changing a repeating TODO's state to DONE remotely from the
agenda fails to change the date when the calendar is open in
another window.

The reason is that `org-recenter-calendar' selects the agenda
window after doing its work, also making the agenda the current
buffer, but caller `org-auto-repeat-maybe' expects the current
buffer to be the Org file that contains the TODO item.

Here's how to reproduce it:

Run `emacs -Q -l setup.el'.
Type `M-x calendar'.
Type `M-x org-agenda', then `a' for weekly agenda.
Move point to first TODO.
Press `t' to try to change TODO state to DONE.

The result is that `Note stored' appears in the echo area but
there is no change in the agenda view or in the scheduled date
in `test-case.org'.

Here is `test-case.org':

------------------------------------------------------------------------

* TODO Foo
  SCHEDULED: <2012-02-17 Fri .+1d>

------------------------------------------------------------------------

And here is `setup.el':

------------------------------------------------------------------------

(setq org-agenda-files '("./test-case.org"))
