Yes, the parser can handle \r\n. Note that they can only be white space
in JSON - they can only be present in string values via escapes.

IDK. I normally use core.autocrlf=false core.eol=lf on Windows. The
editors I use are reasonably well behaved ;-)

What I suggest (see attached) is we run the diff command with
--strip-trailing-cr on Windows. Then we just won't care if the expected
file and/or the output file has CRs.

Not sure what the issue is with pg_bsd_indent, though.
