Need API function to verify authorization/intention of post/page saves for plugin use.

We should have an API function to do this:

Something like post_was_saved_from_admin(). Lot of redundant code to do that in every plugin.

ues save_post, rather than edit_post. edit_post means just that: post was edited... it gets fired when a comment is added or removed, among other things.
