I'm sure the code side of this is trivial; it's a question of why Tom
was objecting. It would probably be better for us to come to a
conclusion before working on this.
On a related note... something else we could do here would be to keep a
last-known-good copy of the config files around. That way if you flubbed
something at least the server would still start. I do think that any
admin worth anything would notice an error from pg_ctl, but maybe others
have a different opinion.
