If we exit a PG_TRY block early via "continue", "break", "goto", or "return", we'll skip unwinding its exception stack. This change moves a couple of such "return" statements in PL/Python out of PG_TRY blocks. This was introduced in d0aa965c0a and affects all supported versions. We might also be able to add compile-time checks to prevent recurrence, but that is left as a future exercise.
