Hi! In this change, you removed most of the error codes for action=edit. There is no link to any other place where to find the errors. Nor does standard errors page list these. The page says "If a module can throw these errors, that's explicitly mentioned in its Possible errors section.", but the edit page doesn't list them anymore. And, besides standard message, for example, I cannot even find info on "editconflict" error anymore anywhere.
