 Replying to [ticket:11474 jeremyclarke]:

 I really like this, and agree that the Settings API needs an error
 reporting system.

 A question: what would happen if the user decides not to fix the cause of
 the validation error immediately? Say, he/she goes off and does something
 else, then navigates back to the plugin's settings page, for example after
 the transient has expired. Would it be useful to automatically re-run the
 register_setting() callback on page load? It seems to me desirable that
 the error messages are persistent until the cause(s) of the error(s)
 is(are) fixed.
