When a file used in the org-agenda is in a narrowed state (org-narrow-to-subtree or similar) and you refresh the agenda buffer via `g', it becomes un-narrowed. This is a very annoying behavior as I tend to narrow to subtrees while editing their contents.
Is this a bug or desired behavior? If the latter, I'll try hunting the missing `save-restriction' down tomorrow. -- Moritz Ulrich
