Fix psql's \sf and \ef for new-style SQL functions.
Some options of these commands need to be able to identify the start
of the function body within the output of pg_get_functiondef().
It used to be that that always began with "AS", but since the
introduction of new-style SQL functions, it might also start with
"BEGIN" or "RETURN". Fix that on the psql side, and add some
regression tests.
Noted by me awhile ago, but I didn't do anything about it.
Thanks to David Johnston for a nag.
