I'm noticing that the latest pgindent run has frequently rejustified
block comments to end in column 80 or 81, causing them to wrap in an
ugly way (at least in emacs). I thought the agreement was to limit
lines to 79 chars max?
For one example see lines 475 ff in /src/backend/access/nbtree/nbtpage.c
--- the first lines of two successive paragraphs in the comment have
been made too long, which they were not before.
I'm not sure about this offhand, but I think that all the cases I've
seen have involved first lines of paragraphs inside block comments.
