It's not that - it happens even with just
int frak =
1;

since it doesn't happen for plain assignments, I think it's somehow related to
code dealing with variable declarations.

It's pretty awful code :(

Oh. I thought we had re-indented the other branches when we modified
pg_bsd_intent substantially in the past, to reduce backpatching pain. But I
guess we just discussed that option, but didn't end up pursuing it.
