Yes, I was just reviewing those threads. IIUC, the current proposal is
to adopt FreeBSD's version of indent as being less buggy and better
maintained than NetBSD's, and then patch it as necessary.

We'd put off the decision what to do exactly until a more suitable time,
but I think that time is now. What I think we ought to do is go ahead
and indent the tree with current pgindent, and then we have a basis for
experimenting with replacement versions and seeing what they'll do
differently. If we can make a decision and adopt any changes within
the next few weeks, I think that that timing will be about the least pain
we can hope for.

If we do anything with as much impact as changing the indentation rule
for string continuations, I will certainly vote for running the new
pgindent over the back branches too. I still bear the scars of dealing
with the comment-reflowing changes that Bruce put in circa 8.1 --- that
broke just about every back-patching effort for the next five years.
I don't want to go through that again.
