Fixed.

Fixed. The other references to RFCs use this syntax indeed.

'\n' gets translated by libc when the output is in text mode.
We discussed this upthread, but maybe it should be a code comment:
added now.

Oops, fixed.

Where is that code?

I've changed to upper case in a couple places and added <acronym> tags,
but depending on the context sometimes lower case feels more consistent.
This is the same as, for instance, ASCII. We display \pset linestyle as
ascii, not ASCII, presumably because everything else in the \pset area
is lower case. But both cases are accepted in input.

Also added a CSV entry in the doc index per Alvaro's suggestion in
https://www.postgresql.org/message-id/20180809202125.r4mdx2jzm7hytetz@alvherre.pgsql
with pointers to psql and COPY.
