Subject: [PATCH] lisp/org.el: Save restrictions in all agenda file buffers.

* lisp/org.el (org-agenda-prepare-buffers): Call
`save-restriction'/`save-excursion' for every buffer in the agenda
instead of just once for the current buffer. Use `with-current-buffer'
instead of `set-buffer'/`save-excursion'.
